Anti-CD50/ICAM3 Antibody

ICAM3 (Intercellular adhesion molecule 3) is also named as CD50, CDw50 and ICAM-R. ICAM3 is a member of the intercellular adhesion molecule (ICAM) family. ICAM3, being expressed constitutively on T cells and other leukocytes, is a potent signalling molecule and a major ligand in the initiation of T cell-mediated immune responses (PMID: 1448173, PMID: 11812993) . ICAM3 is the natural ligand for both DC-SIGN and L-SIGN (PMID: 17570115) . ICAM3 is abundantly and constitutively expressed in all leukocytes and is probably the most important ligand for LFA-1 in initiating immune responses, and ICAM3 is a typical type I transmembrane glycoprotein (PMID: 39991572) . The promoter region of ICAM3 can be bound by co-transcription factors such as ETs and C/EBP, promoting macrophage maturation as well as monocyte extravasation (PMID: 22479382) . ICAM3 is widely expressed not only in lymphocytes such as T and B cells but also in many endothelial cells and dendritic cells (PMID: 39991572) .
