Description

SLAMF7 (signaling lymphocytic activation molecule family member 7), also known as CS1, CRACC and CD319, is a single-pass type I transmembrane glycoprotein that belongs to the SLAM subfamily of the CD2 protein family of the Ig (immunoglobulin) superfamily. Most SLAM family members function as adhesion molecules and co-receptors for lymphocyte activation and mediate tyrosine phosphorylation signals. SLAMF7 contains 1 Ig-like V-type and 1 Ig-like C2-type domains in the extracellular region and 2 ITSM (immunoreceptor tyrosine switch motifs) in the cytoplasmic region. SLAMF7 is expressed on the surface of NK cells, CD8+ T cells, activated B cells, and mature dendritic cells. It interacts homophilically through its Ig-like V type domain to induce NK, CTL, and B cell activation. SLAMF7 may play a role in the regulation of B cell proliferation during immune responses. SLAMF7 is also implicated in the activation of NK cell-mediated cytotoxicity. SLAMF7 can exert activating or inhibitory effects on immune cells dependent on the cellular context and the availability of signaling effector/adaptor proteins.
