CD156c, also known as A Disintegrin and metalloproteinase domain-containing protein 10 (ADAM10), is a 748 amino acid type I membrane glycoprotein ubiquitously expressed on most of the cell types. It consists of multiple functional domains, including a N-terminal prodomain, catalytic domain, cysteine-rich domain, transmembranous domain, and cytoplasmic domain. It is secreted as a precursor protein and becomes as the activate/mature form through removing the ADAM10 prodomain by proprotein convertase 7 and furin. ADAM10 functions as metalloproteinase to cleave several molecules including Notch, pro-TNF-α, amyloid precursor protein, myelin basic protein, and type IV collagen. It mediates the release of several cell adhesion molecules such as vascular endothelial cadherin or L-selectin to regulate endothelial permeability and leukocyte transmigration. Dysregulation of ADAM activity may contribute to the pathogenesis of vascular diseases.
