Recombinant Human SLAMF6 protein, His-tagged

Cat.No.: SLAMF6-241H
Product Overview: Recombinant Human SLAMF6(Gln22-Met226) fused with His tag at C-terminal was expressed in HEK293.
Description: NTB-A, also known as Ly108 and SLAMF6, is a 60 kDa type I transmembrane glycoprotein in the SLAM subgroup of the CD2 family. Mature human NTB-A consists of a 205 amino acid (aa) extracellular domain (ECD) with one Ig-like V-set and one Ig-like C2-set domain, a 21 aa transmembrane segment, and an 84 aa cytoplasmic domain with two immunoreceptor tyrosine-based switch motifs (ITSMs). An alternatively spliced isoform is truncated in the cytoplasmic domain and lacks the two ITSMs. Within the ECD, human NTB-A shares 48% aa sequence identity with mouse and rat NTB-A. The ECD of human NTB-A shares 19%-34% aa sequence identity with comparable regions of human 2B4, BLAME, CD2F-10, CD84, CD229, CRACC, and SLAM. NTB-A is expressed on the surface of NK, T, and B lymphocytes as well as eosinophils. It interacts homophilically through weak associations between the Ig-V domains. NTB-A functions as an activating coreceptor on NK and T cells. Tyrosine phosphorylation in the membrane proximal ITSM enables specific association with EAT-2, an interaction that is required for NTB-A mediated cytotoxicity of NK cells. Phosphorylation-dependent NTB-A association with SAP is required for full production of IFN-gamma by NK cells. This interaction is independent of EAT-2 binding and appears to involve the membrane distal ITSM. NTB-A deficient mice show weakened Th2 responses and elevated levels of neutrophil-derived inflammatory mediators. In B cells, NTB-A modulates immunoglobulin class switching and the balance between tolerance and autoimmunity. In addition, NTB-A binds to the influenza virus hemagglutinin (HA) protein which co-stimulates NK cell activation. The Vpu protein encoded by HIV-1 interferes with NTB-A glycosylation and cell surface expression.
