Background
CD5 is a type I transmembrane glycoprotein of the scavenger receptor cysteine-rich family. CD5 is expressed on a majority of thymocytes, mature T cells, B cell subsets, and peripheral blood dendritic cells. CD5 may act as a receptor in regulating T-cell proliferation. It functions as a negative regulator of TCR signaling during thymocyte development.
