Verification Image

Western blot analysis of extracts from U251 (lane 2(20μg), U251 (lane 3(40μg), using Melanoma gp100 Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Background

Function：Forms physiological amyloids that play a central role in melanosome morphogenesis and pigmentation. The maturation of unpigmented premelanosomes from stage I to II is marked by assembly of processed amyloidogenic fragments into parallel fibrillar sheets, which elongate the vesicle into a striated ellipsoidal shape. In pigmented stage III and IV melanosomes, the amyloid matrix serves as a platform where eumelanin precursors accumulate at high local concentrations for pigment formation. May prevent pigmentation-associated toxicity by sequestering toxic reaction intermediates of eumelanin biosynthesis pathway; Represents a potent melanoma-specific antigen. Among melanoma non-mutated self-peptides, G9-154 (KTWGQYWQV), G9-209 (ITDQVPFSV) and G9-280 (YLEPGPVTA), appear to act as immunodominant common epitopes that stimulate anti-tumor immune response mediated by HLA-A-restricted cytotoxic T cells

Subcellular Localization：Endoplasmic reticulum membrane; Single-pass type I membrane protein; Golgi apparatus, cis-Golgi network membrane; Single-pass type I membrane protein; Endosome, multivesicular body; Melanosome; Extracellular vesicle; Secreted

Expression：
Tissue_specificity:It is typically expressed at low levels in quiescent adult melanocytes, but is overexpressed in proliferating neonatal melanocytes and during tumor growth. It is also overexpressed in melanoma. Some expression has also been found in dysplastic nevi.

Isoforms & Post-Translational Modification：P40967 has 5 isomers: P40967-1: 70255 Da (predicted); P40967-2: 70949 Da (predicted); P40967-3: 60581 Da (predicted); P40967-4: 66035 Da (predicted); P40967-5: 66729 Da (predicted).
N- and O-glycosylated. A small amount of P1/P100 (major form) undergoes glycosylation in ER and Golgi compartments to yield P2/P120 (minor form). The mature P2 form leaves the trans-Golgi network and is mainly targeted to stage I melanosomes via the plasma membrane and clathrin-mediated endocytosis. Stage II melanosomes harbor only Golgi-modified fragments that are derived from M-alpha and that bear sialylated O-linked oligosaccharides. O-glycosylation of the RPT region is a conserved feature likely involved in amyloid sheet separation via electrostatic repulsion;Undergoes multiple proteolytic processing. In a post-Golgi prelysosomal compartment, P2 is cleaved by a furin-like proprotein convertase (PC) into two disulfide-linked subunits: a large lumenal subunit, M-alpha/ME20-S, and an integral membrane subunit, M-beta. Despite cleavage, only a small fraction of M-alpha is secreted, as most M-alpha and M-beta remain associated with each other intracellularly via a disulfide bond (PubMed:11694580, PubMed:12732614, PubMed:15096515, PubMed:15695812, PubMed:17991747). Once targeted to stage I melanosomes, beta-secretase BACE2 cleaves the M-beta fragment to release the amyloidogenic luminal fragment containing M-alpha and a small portion of M-beta N-terminus (PubMed:23754390). M-alpha is further cleaved by metalloproteinases, likely ADAM10 or ADAM17, and still unknown proteases to yield subfragments that ultimately assemble into amyloid fibrils (PubMed:19047044). The C-terminal fragment of M-beta is processed by the gamma-secretase complex to release a short intracytoplasmic domain (PubMed:19047044)

Subunit：Homodimer; disulfide-linked. Dimerization in the endoplasmic reticulum and early Golgi prevents premature fibril formation. The dimers are resolved to monomers in late- or post-Golgi compartments (PubMed:26694611). Heterooligomer; amyloid-type. Processed amyloidogenic fragments assemble into fibrils that further organize into beta-sheet quaternary amyloid structures (PubMed:28272432, PubMed:30988362). Interacts (via luminal C-terminal fragment) with CD63; this is important for sorting of the luminal fragment in tetraspanin rich microdomains in stage I melanosomes to prevent premature lysosomal degradation (PubMed:21962903). Interacts with APOE; this allows the loading of the luminal fragment on ILVs to induce fibril nucleation (PubMed:26387950). Interacts with MLANA (PubMed:15695812)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
