ALCAM/CD166

ALCAM (CD166), a cell surface glycoprotein, is a cell adhesion molecule of the immunoglobulin superfamily. ALCAM is expressed by various cell types, such as leukocytes and endothelial cells (ECs). ALCAM can bind to the T cell-expressed scavenger receptor CD6, endothelial L1CAM, and galectin-8. ALCAM regulates diverse pathophysiological processes, including T cell activation, leukocyte trafficking, and angiogenesis. ALCAM is a prognostic marker of cancers. ALCAM promotes tumor growth by controlling cell proliferation, adhesion, migration and invasion^[1][2].
