Mitofusin-1 (MFN1) is a mediator of mitochondrial fusion. This protein and mitofusin 2 are homologs of the Drosophila protein fuzzy onion (Fzo). Mitofusins are large predicted GTPases located in outer mitochondrial membrane. They are essential for outer membrane fusion by interacting with each other to facilitate mitochondrial targeting. The mitofusins are the first known protein mediator of mitochondrial fusion, and mediate developmentally regulated post-meiotic fusion of mitochondria.Mfn1 is required on adjacent mitochondria to mediate fusion via interactions of a heptad repeat region that mediates oligomerization of the protein.

IL-6 is a pleiotropic cytokine that plays an important role in host defense by regulating immune and inflammatory responses. Produced by T cells, monocytes, fibroblasts, endothelial cells and keratinocytes, IL-6 has diverse biological functions. It stimulates B cell differentiation and antibody production, synergizes with IL-3 in megakaryocyte development and platelet production, induces expression of hepatic acute-phase proteins, and regulates bone metabolism. IL-6 signals through the IL-6 receptor system that consists of two chains, IL-6Rα and gp130. Murine IL-6 is inactive on human cells, while both human and murine are equally active on murine cells. Recombinant Murine IL-6 is a 21.7 kDa protein containing 188 amino acid residues.

Visfatin is a 55 kDa protein produced and secreted primarily by white adipose tissue.  Recently, visfatin was isolated from visceral fat deposits and shown to possess insulin-mimetic activity.  Like insulin, visfatin exerts hypoglycemic effects by interacting with the insulin receptor.  The binding affinity of visfatin for the insulin receptor is similar to that of insulin, but it does not compete with insulin, suggesting that the two proteins interact with different receptor sites.  The circulating levels of visfatin are much lower than those of insulin and are not affected by feeding, implying that the hypoglycemic effect of visfatin may not be of physiological importance.  The plasma visfatin levels, like those of leptin, correlate positively with the percent of body fat, and increase during the development of obesity. Receptors for both leptin (Ob-R) and visfatin (i.e. the insulin receptor) are expressed by neurons within the arcuate nucleus of the hypothalamus, a brain area that plays a pivotal role in the regulation of energy metabolism.  Although the metabolic function of visfatin is still unknown, it appears that this newly identified adipocytokine might play an important role, similar to that of leptin, in the regulation of body weight, i.e. as an afferent signal reflecting excess body fat.  The PBEF gene encodes a polypeptide of 491 amino acid residues. The secreted form of this polypeptide, i.e. visfatin, contains 465 residues and lacks the first 26 N-terminal residues of the PBEF gene product. The 491-residue form has been shown to be a nicotinamide phosphoribosyltransferase, a cytosolic enzyme involved in NAD biosynthesis. The amino acid sequence of visfatin is highly conserved across different species and shows no homology to any known protein. It contains 5 cysteine residues, of which only two of them appear to be involved in disulfide bridge formation. Recombinant human Visfatin is a 52.6 kDa protein containing 466 amino acid residues (isoform 1).

CSN8 Antibody: The COP9 signalosome (CSN) is an evolutionarily conserved protein complex of the eight subunits that interacts with deubiquitinating enzymes and protein kinases and is highly homologous to the lid sub-complex of 26S proteasome. The CSN complex is an essential regulator of the ubiquitin conjugation pathway by mediating the deneddylation of the SCF-type E3 ligase complexes, which leads to a decrease in ubiquitin ligase activity of SCF-comlpexes such as SCF, CSA or DDB2. It is also involved in phosphorylation of p53, c-jun/JUN, ITPK1 and IRF8/ICSBP, possibly via its association with CK2 and PKD kinases. CSN8 encodes the smallest and the least conserved but first identified subunit of CSN. Recent studies show CSN8 is essential for Drosophila development and is essential for peripheral T cell homeostasis and antigen receptor-induced entry into the cell cycle from quiescence.

This antibody is predicted to react with mouse and rat based on sequence homology. Ubiquitin-like molecules and can be ligated to target proteins in a similar manner as ubiquitin. However, covalent attachment of UBLs does not result in degradation of the modified proteins. SUMO1 modification is implicated in the targeting of RANGAP1 to the nuclear pore complex, as well as in stabilization of I-kappa-B-alpha from degradation by the 26S proteasome. Like ubiquitin, UBLs are synthesized as precursor proteins, with 1 or more amino acids following the C-terminal glycine-glycine residues of the mature UBL protein. Thus, the tail sequences of the UBL precursors need to be removed by UBL-specific proteases, such as SENP6, prior to their conjugation to target proteins . SENPs also display isopeptidase activity for deconjugation of SUMO-conjugated substrates .

Myelin/oligodendrocyte glycoprotein (MOG), a 26-to 28-kDa glycoprotein, a myelin antigen at the outer surface of the central nervous system (CNS) myelin sheath, which may trigger T-cell as well as B-cell responses. It therefore constitutes a pivotal target for autoimmune responses, which result in inflammation and also demyelination in the CNS. Its presence on the outer- most lamellae of mature CNS myelin and its late appearance during myelinogenesis suggest that it contributes to myelin maturation or maintenance. 10 isoforms of MOG produced by alternative splicing have been described, and heterodimers may be formed between the different isoforms. Defects in MOG are the cause of narcolepsy type 7 (NRCLP7), a neurological disabling sleep disorder characterized by excessive daytime sleepiness, sleep fragmentation, symptoms of abnormal rapid-eye-movement (REM) sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis. Role of MOG in the pathogenesis of multiple sclerosis (MS) has been reported but remains to be clarified.

Studies have demonstrated that PR39, a proline/arginine rich 39 amino acid antibacterial peptide originally derived from porcine bone marrow, exhibits a broad spectrum of biological activities, including the ability to induce angiogenesis and to limit inflammatory damage in a variety of animal models. The angiogenic effect is in part explained by the ability of PR39 to inhibit proteasome-dependent degradation of the transcription factor HIF-1a, while anti-inflammatory activity is associated with inhibition of IκBα degradation that in turn prevents activation of NFκB-dependent gene expression. The activities of PR39 reside in the N-terminal portion of the molecule encompassed by PR11. The most recent findings have demonstrated that PR39 is a non-competitive and reversible inhibitor of the proteasome function, which is achieved by a unique allosteric mechanism allowing for specific inhibition of degradation of selected proteins without affecting total proteasome-dependent proteolysis. A proline-arginine-rich 11 amino acid peptide derived from the naturally occurring peptide antibiotic PR39. PR39 has been shown to act as an inhibitor of both 20S and 26S proteasomes with proposed selectivity for the inhibition of the degradation of IκBα, HIF-1a and certain other proteins. PR39 has been reported to inhibit the proteasomal degradation of IκBα without effecting overall proteasome activity, or degradation of p21Cip1/Waf1 and c-fos, cell-cycle genes regulated by proteasome-dependent degradation. In vitro studies have demonstrated PR39 to be an efficient inhibitor of all three activities of the 20S proteasome. Unlike MG132 and lactacystin, long-term exposure to PR39 shows little toxicity or induction of HSP-70. In mouse models of myocardial infarction it has been shown that infusion with PR11 results in a significant reduction of myocardial infarct size. PR39, PR11 and related peptides may therefore provide novel means to regulate cellular function and the control of NF-κB-dependent gene expression for therapeutic purposes.

The RING-type zinc finger motif is present in a number of viral and eukaryotic proteins and is made of a conserved cysteine-rich domain that is able to bind two zinc atoms. Proteins that contain this conserved domain are generally involved in the ubiquitination pathway of protein degradation. RNF141 (ring finger protein 141), also known as ZFP26 or ZNF230, is a 230 amino acid protein that contains one RING-type zinc finger. Expressed as two isoforms (isoform 1 and isoform 2) due to alternative splicing events, RNF141 is thought to function as a transcription factor during spermatogenesis. While isoform 2 is expressed in brain, heart, pancreas, kidney and skeletal muscle, isoform 1 is expressed primarily in testis, suggesting that isoform 1 functions during spermatogenesis. In addition, RNF141 is not expressed in azoospermic (infertile) men, further implicating an important role for RNF141 in testis development and male fertility.
