Description

Mouse Monoclonal Antibody

OJ79c recognizes human Cell surface glycoprotein MUC18, also known as CD146, Cell surface glycoprotein P1H12, Melanoma cell adhesion molecule (MCAM) or S-endo 1 endothelial-associated antigen. CD146 is a 646 amino acid single pass type 1 transmembrane glycoprotein with a calculated molecular mass of ~72 kDa. However due to extensive N-linked glycosylation CD146 migrates in polyacrylamide gels with an apparent molecular mass of ~118 kDa. CD146 is a member of the immunoglobulin superfamily bearing 2 V-type Ig-like and 3 C-type Ig-like domains. CD146 is expressed by all endothelial cells and by melanoma cells and appears to act as an adhesion molecule (UniProt: P43121). Expression in melanoma may be linked to tumor progression (Lehmann et al. 1989).Mouse anti Human CD146 antibody, clone OJ79c is highly expressed on pericytes and has been utilized for the identification of perivascular mesenchymal precursor cells from cardiac muscle using flow cytometry (Chen et al. 2014).

CD146, also known as MCAM (Melanoma Cell Adhesion Molecule), is an integral membrane glycoprotein belonging to the immunoglobulin superfamily. It is heavily glycosylated, with more than 50% of its mass derived from carbohydrates. CD146 is primarily expressed on endothelial cells at cell-cell junctions, playing a crucial role in cell adhesion and the cohesion of the endothelial monolayer in vascular tissue. In addition to endothelial cells, CD146 is expressed on bone marrow fibroblasts, mesenchymal stromal cells, endometrial stromal cells, and some tumors, particularly melanoma. It has also been observed on a subset of circulating T cells and activated lymphocytes, but not on circulating endothelial cells, as indicated by the absence of other endothelial markers such as CD31 and CD51/61. CD146 functions as a calcium-independent cell adhesion molecule and may also act as a signal transduction molecule. It is involved in the recruitment of Fyn kinase and the subsequent tyrosine phosphorylation of intracellular proteins, which are important for actin cytoskeleton assembly. This signaling role includes triggering tyrosine phosphorylation of FYN and PTK2 and causing a transient increase in intracellular calcium concentration. In the context of cancer, CD146 expression may facilitate the interaction of melanoma cells with the vascular system, enhancing hematogenous tumor spread. Additionally, CD146 could serve as an adhesion molecule active in neural crest cells during embryonic development, highlighting its diverse roles in both normal physiological processes and disease states.
