Description

The MAb P1H12 recognizes CD146 also known as MUC18, s-endo, Endo-CAM and Mel-CAM, which is a member of the Ig superfamily of proteins. The expression of CD146 is found on endothelial cells, bone marrow fibroblasts and some tumors (especially melanoma). Recently mesenchymal stromal cells and endometrial stromal cells have also been shown to express CD146. The presence of CD146 on circulating blood cells have been confined to a subset of T cells rather than circulating endothelial cells, as expression of other endothelial markers (CD31 and CD51/61) is negative. Expression can be found on activated lymphocytes. The protein is heavily glycosylated with more than 50% of the mass from carbohydrates. The antibody P1H12 has been reported to crossreact to mouse, rabbit, canine, but not rat.

CD146 (MCAM) is an integral membrane glycoprotein belonging to the immunoglobulin superfamily. CD146 is expressed at cell-cell junctions in all endothelial cells, and has also been observed in other normal and malignant cell types. In addition to its recognized role as a calcium-independent cell adhesion molecule, CD146 may also act as a signal transduction molecule in the recruitment of Fyn kinase, and in the subsequent tyrosine-phosphorylation of intracellular proteins involved in actin cytoskeleton assembly. CD146 plays a role in cell adhesion, and in cohesion of the endothelial monolayer at intercellular junctions in vascular tissue. CD146 expression may allow melanoma cells to interact with cellular elements of the vascular system, thereby enhancing hematogeneous tumor spread. Further, CD146 could be an adhesion molecule active in neural crest cells during embryonic development. CD146 acts also as surface receptor that triggers tyrosine phosphorylation of FYN and PTK2, and a transient increase in the intracellular calcium concentration.
