Signal-Regulatory Protein Alpha, SIRPA belongs to the signal-regulatory-protein (SIRP) family, as well as theimmunoglobulin super family. The members of the SIRP family are receptor-type transmembrane glycoproteins which areinvolved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. SIRPA can bephosphorylated by tyrosine kinases. The phospho-tyrosine residues of this PTP have been shown to recruit SH2domain containing tyrosine phosphatases (PTP), and perform as substrates of PTPs. SIRPA take part insignal transduction mediated by a variety of growth factor receptors. CD47 has been shown to be a ligand forSIRPA.

SIRPA Rat Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 350 amino acids (32-373a.a) and having a molecular mass of 38.5kDa. (Migrates at 57-70kDa on SDS-PAGE under reducing conditions). SIRPA is fused to an 8 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
