Description / CRTAM
Human CRTAM is a 393 amino acid (aa), 80 kDa type I transmembrane glycoprotein. CRTAM is a homodimer on the cell surface but does not show homotypic binding in trans. The high affinity of CRTAM/IGSF4 adhesion allows CRTAM to disrupt IGSF4 homotypic interactions. IGSF4 and T cell receptor co-engagement of CRTAM-expressing CD8+ cells induces increased IFN-gamma or IL-22 production. A role in cancer surveillance through NK cell-mediated rejection of IGSF4-expressing tumors has been proposed. IGSF4 is expressed broadly, including on epithelia, neurons, a subset of tonsillar B cells and a rare splenic T zone-restricted BCDA3+ dendritic cell population which interacts with CRTAM.
