Background: SIRP gamma/CD172g

Signal-regulatory protein gamma/beta 2 (SIRP gamma/beta 2) is a 45-47 kDa type 1 transmembrane glycoprotein and member of the immunoglobulin superfamily and SIRP family of proteins. Human SIRP gamma/beta 2 is synthesized as a 387 amino acid (aa) precursor that contains a 28 aa signal sequence, a 332 aa extracellular domain (ECD), a 23 aa transmembrane segment, and a 4 aa cytoplasmic tail. The ECD contains two Ig-like C1-type domains, one Ig-like V-type domain, and four potential sites for N-linked glycosylation. There are four named isoforms for human SIRP gamma/beta 2. Human SIRP gamma/beta 2 has no orthologs, but it is 75% aa identical to SIRP beta. It is expressed in the liver and at very low levels in brain, heart, lung, pancreas, kidney, placenta, and skeletal muscle. SIRP gamma/beta 2 is also expressed on CD4  ⁺ T-cells, CD8  ⁺ T-cells, and activated NK cells.
