Background: CD53

CD53, also known as TSPAN25, is a 35 kDa‑40 kDa cell surface and endosomal membrane glycoprotein in the tetraspanin superfamily. CD53 is widely expressed on hematopoietic cells. Ligation of CD53 promotes cell activation and survival as well as homotypic cell‑cell adhesion. CD53 associates with other tetraspanins, MHC class I and II molecules, and integrin alpha 4 beta 1. Human CD53 shares 81%‑83% aa sequence identity with mouse and rat CD53.
