Description

SLAMF6 (signaling lymphocytic activation molecule family member5), also known as NTB-A and CD352, 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. SLAMF6 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. SLAMF6 is expressed on the surface of NK, T, and B cells as well as eosinophils. It associates homophilically through weak interactions between the Ig­like V-type domains. SLAMF6 functions as an activating co-receptor on NK and T cells. Tyrosine phosphorylation in the membrane proximal ITSM enables specific association with the adaptor molecules, leading to SLAMF6 mediated cytotoxicity of NK cells and the production of IFN­γ by NK cells. SLAMF6 may also mediate inhibitory signals in NK cells from X-linked lymphoproliferative patients.SLAMF6 deficient mice show weakened Th2 responses and elevated levels of neutrophil­derived inflammatory mediators. On B cells, SLAMF6 modulates Ig class switching and the balance between tolerance and autoimmunity.
