Interleukin 6 (IL6) is a multifunctional 24 kD protein originally discovered in the medium of RNA stimulated fibroblastoid cells. It is upregulated by IL1, TNF, PDGF, IFN beta, TNF alpha, NGF, IL17 and downregulated by glucocorticoids IL4, TGF beta. IL6 appears to be directly involved in the responses that occur after infection and cellular injury, and it may prove to be as important as IL1 and TNF alpha in regulating the acute phase response. IL6 has also been implicated in regulating adipose mass. IL6 is reported to be produced by fibroblasts, activated T cells, activated monocytes or macrophages and endothelial cells. It acts upon a variety of cells including fibroblasts, myeloid progenitor cells, T cells, B cells and hepatocytes. In addition, IL6 appears to interact with IL2 in the proliferation of T lymphocytes. IL6 potentiates the proliferative effect of IL3 on multipotential hematopoietic progenitors.

CD95, also known as FAS or APO-1, is a 36 kDa cell surface type I- membrane glycoprotein with an apparent molecular weight of 44 kDa on SDS-PAGE. CD95 is a member of the TNF receptor family, which includes TNFR-1, TNFR-2, CD27, CD30 and CD40. Binding of CD95 Ligand to CD95 or crosslinking of CD95 by anti-CD95 monoclonal antibodies leads to apoptosis of CD95 expressing cells. CD95 belongs to a subgroup of family members that have a death domain (DD) which contains 70 amino acids near the carboxyl-terminal region of the molecule. The binding of adaptor molecules to this DD is responsible for transmitting the death signal for apoptosis. Stimulation of CD95 results in aggregation of its DD, leading to the recruitment of FADD and caspase-8 that together with the receptor form the death-inducing signaling complex (DISC).

N ethylmaleimide sensitive factor (NSF) is an ~83 kDa protein (predicted MW) which was initially isolated based on its ability to restore intercisternal Golgi transport to N ethylmaleimide treated membranes. NSF was subsequently discovered to be involved in a variety of membrane fusion events. NSF is an ATPase with two ATP binding domains that are essential for membrane fusion and homo oligomerization. In order to interact with target membranes, NSF requires another set of soluble proteins called Soluble NSF attachment proteins (SNAPs). NSF has been shown to play a prominent role in synaptic vesicle fusion. Together with synaptotagmin and a SNAP, NSF modulates the interaction of SNAP25, VAMP, and syntaxin, in an ATP dependent manner, to form a complex with a sedimentation coefficient of 20 S. This complex may represent an intermediate involved in synaptic vesicle docking and fusion.

Members in the TNF superfamily regulate immune responses and induce apoptosis. A novel member in the TNF family was recently identified by several groups and designated BAFF (for B cell Activating Factor belonging to the TNF Family), BLyS (for B Lymphocyte Stimulator), TALL1 (for TNF- and ApoL- related Leukocyte-expressed Ligand), and THANK (for TNF Homologue that Activate Apoptosis, NFkB and c-jun N-terminal Kinase). BAFF/BLyS was characterized as a B cell stimulator since it induced B cell proliferation and immunoglobulin secretion. Two receptors for BAFF were recently identified and designated TACI and BCMA. BAFF and its receptors are involved in the development of systemic lupus erythaematosus and other B cell associated autoimmune diseases. Like TNFa and TRAIL,THANK was shown to activate NF-kB and c-jun N terminal kinase (JNK) and to induce apoptosis.

Nuclear factor kappa B (NF-kB) is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses. NF-kB mediates the expression of a great variety of genes in response to extracellular stimuli. NF-kB is associated with IkB proteins in the cell cytoplasm, which inhibit NF-kB activity. Phosphorylation of I-kB by IkB kinase (IKK) complex leads to degradation of I-kB and activation of NF-kB. The IKK complex contains IKKa,IKKb, and IKKg. A novel IKK related kinase was recently identified and designated TBK1 (TANK-binding kinase 1), NAK (NF-kB-activating kinase), and T2K. NAK/TBK1 activates IKKb through direct phosphorylation. NAK/TBK1is activated by growth factors and PMA and mediates IKK and NF-kB activation in response to growth factors. NAK/TBK1 functions upstream of NIK and the IKK complex. NAK/TBK1 is also critical in protecting embryonic liver from apoptosis.

There are two kinds of IGF receptors based on their relative affinities for IGFI versus IGFII. The IGFI receptor prefers IGFI over IGFII and weakly binds insulin. IGFI receptor is a disulfide-linked heterotetrameric transmembrane protein consisting of two alpha (130 kD) and two beta (95 kD) subunits. Both the alpha and beta subunits are encoded within a single receptor precursor cDNA. The IGFI receptor is therefore similar in structure to the insulin receptor. The proreceptor polypeptide is proteolytically cleaved and disulfide-linked to yield the mature heterotetrameric receptor. The alpha subunit of the IGFI receptor is extracellular while the beta subunit has an extracellular domain, a transmembrane domain and a cytoplasmic tyrosine kinase domain. The IGFI receptor is highly expressed in all cell types and tissues. Essentially all of the biological activities of IGFI and II have been shown to be mediated via the IGFI receptor.

Perforin is one of the major cytolytic proteins of cytolytic granules. One of the main pathways of lymphocyte mediated cytolysis entails the secretion onto target membranes of cytolytic granules contained in cytolytic effector lymphocytes of T-cell or NK-cell type. Perforin is a cytolytic mediator and is stored in and released by cytoplasmic granules. Perforin (PRF) is involved in the killing mediated by cytotoxic lymphocytes which represents an important mechanism in the immune defense against tumors and virus infections. Human PRF is a 555 amino acid protein with a 21 amino acid signal peptide. It has a molecular weight of 70 to 75 kD. PRF is a pore forming protein with a mechanism of transmembrane channel formation similar to C9 and homology between perforin and C9 has been demonstrated at their respective functionally conserved regions. Studies show that perforin is expressed only in killer cell lines and not in helper T lymphocytes or other tumor cells tested.

Superoxide dismutase (SOD) is responsible for the elimination of cytotoxic active oxygen by catalyzing the dismutation of the superoxide radical to oxygen and hydrogen peroxide. There are three SOD isoenzymes in mammalian cells. They are: extracellular SOD (EC SOD), copper and zinc-containing SOD (CuZn SOD) and manganese-containing SOD (Mn SOD). The CuZn form contains Cu and Zn ions and exists as a 32 kDa dimer in the cytosol. Mn SOD is an 80 kDa tetramer that contains Mn ion and resides in the mitochondrial matrix. Mn SOD is a tumor necrosis factor (TNF)- inducible enzyme that protects cells from TNF-mediated apoptosis via superoxide anion detoxification and the subsequent regulation of apoptosis through cytochrome c release and the modulation of the redox state of the mitochondria. Mn SOD has also been shown to be a tumor suppressor in human breast cancer. Overexpression of this enzyme protects neurons from NMDA- and nitric oxide-induced neurotoxicity.

Basic fibroblast growth factor (bFGF), also known as FGF2, is expressed by endothelial cells and is a mediator of angiogenesis. bFGF also has cardioprotective functions during heart injury. The application of bFGF is a critical component for embryonic stem cell culture systems and is necessary for maintaining cells in an undifferentiated state. Degredation of the full length bFGF N-terminus results in a truncated bFGF147aa protein, when the protein is isolated from biological sources. The N-terminus extensions influence the localization of bFGF within the cell, but do not affect the biological activity of bFGF. Therefore, there are no detectable differences in biological activity between the full length bFGF-154aa and the truncated bFGF-147aa recombinant proteins.

Interleukin-33 (IL-33) is a recently identified member of the IL-1 family of cytokines whose other members include IL-1, IL-1Ra and IL-18 (1,2). Its receptor has been shown to be ST2, an IL-1 receptor family member that also acts as a negative regulator of TLR-IL-1R signaling (1,3) and IL-1R accessory protein (IL-1RAcP) (4). Receptor binding of IL-33 activates NF-B and MAP kinases and induces the expression of TH2-associated cytokines such as IL-4, IL-5 and IL-6. Prolonged IL-33 treatment of mice led to the development of eosinophilia, splenomegaly, and severe pathological changes in mucosal organs such as lungs, esophagus and small intestine (2). Recent experiments have shown that IL-33 can also co-localize with heterochromatin and possesses transcriptional repressor activities, indicating that IL-33 may function as both a proinflammatory cytokine and an intracellular nuclear factor with transcriptional regulatory properties (5).

Bassoon is a 420 kDa protein that is a localized at the presynaptic nerve terminals and is believed to play a role in the structural and functional organization of the synaptic vesicle cycle. Bassoon does not belong to any known protein families. It has been found in rat and mouse with sequence identity of the two proteins at 96%. The human BASSOON gene has recently been cloned and localized. Bassoon is predicted to contain two double-zinc fingers, three coiled-coil regions, and two polyglutamine domains. The polyglutamine domains in the C-terminus are of interest, since it is known that for some human proteins, such as Huntingtin, abnormal amplification of this region can cause late-onset neurodegeneration. Bassoon is concentrated at sites opposite to postsynaptic densities in synaptic terminals and in cultured neurons, it is found to colocalize with GABA (A) and glutamate (GluR1) receptors.Another presynaptic protein, Piccolo was found to colocalize with Bassoon in cultured hippocampal neurons. These observations suggested that they serve specific functions at synaptic junctions and may be involved in organization of the cytoskeleton at the site of neurotransmitter release.

CD254, also known as RANKL, TNFSF11, TRANCE, OPGL and ODF, is a type II membrane protein of the tumor necrosis factor (TNF) superfamily, and affects the immune system and control bone regeneration and remodeling. RANKL is the ligand of nuclear factor (NF)-κB (RANK). When RANKL binds to RANK, it will undergo trimerization and then bind to an adaptor molecule TNF receptor-associated factor 6 (TRAF6). This results in the activation of several downstream signaling cascades, including the NFκB, mitogen-activated protein kinases (MAPK), activating protein 1 (AP-1), and nuclear factor of activated T cells (NFATc1), resulting in the formation of multinucleated bone-resorbing osteoclasts. RANKL is widely expressed in skeletal muscle, thymus, liver, colon, small intestine, adrenal gland, osteoblast, mammary gland epithelial cells, prostate and pancreas.

Lysosomal enzymes containing one or two mannose 6-phosphate (man6P) moieties are moved about in the cell by two distinct but interconnected cycles by means of 300 kDa cation-independent mannose 6-phospate receptors (MPR). MPR cycles and transports newly synthesized lysosomal enzymes between the TGN and late endosomes / early lysosomes. It also cycles and transports extracellular lysosomal enzymes between the plasma membrane and early endosomes via clathrin coated vesicles. The bulk of the MPR protein is in the extracellular/lumenal domain. The entire pool of MPRs cycles between these cellular compartments every 3 hours. The steady state distribution of MPR's is predominantly within late endosomes, fewer in the trans Golgi network and ~5-10 % at the cell surface. In addition to its man6P binding activity, the MPR contains a separate binding site for the type II insulin-like growth factor and is capable of binding both man6P and IGF-II simultaneously. An ~240 kDa soluble, truncated form, representing the extracellular domain of the protein, has also been found circulating in serum and is capable of binding both ligands.
