Name :
Human SLAMF3 Protein, ECD (Extracellular Domain), Fc-fusion, Recombinant
Description :
SLAMF3 (signaling lymphocytic activation molecule family member 3), also known as Ly9 and CD229, 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. SLAMF3 contains 2 Ig-like V-type and 2 Ig-like C2-type domains in the extracellular region and 2 ITSM (immunoreceptor tyrosine switch motifs) in the cytoplasmic region. SLAMF3 is expressed on lymphocytes, thymocytes, and more weakly on NK cells. SLAMF3 cell surface expression on lymphocytes surface is differentially regulated within the SLAM family members. SLAMF3 is a pan-lymphocyte marker and antibodies against it are able to down-regulate T-cell activation. Homophilic interactions between SLAMF3 are mediated through its Iglike domains and involved in the immunological synapse. Antigen stimulation of lymphocytes induces SLAMF3 clustering to the sites of T cell and B cell contact. Two tyrosines in the cytoplasmic domain are required for association with adaptor proteins and internalization. It has been reported that human and mouse SLAMF3 show crossspecies binding.
Gene Symbol :
The recombinant human SLAMF3-Fc fusion protein is expressed as a 540-amino acid protein consisting of Lys48 – Arg359 region of SLAMF3 (UniProt accession #Q9HBG7) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.
