Specificity

Detects human SIRP alpha/CD172a in direct ELISAs and Western blots. In direct ELISAs, 50-100% cross-reactivity with recombinant human (rh) SIRP beta1 and no cross-reactivity with rhSIRP beta2 is observed. In Western blots, approximately 10% cross-reactivity with rhSIRP beta1 and no cross-reactivity with rhSIRP beta2 is observed.

Background: SIRP alpha/CD172a

SIRP alpha (Signal regulatory protein alpha; also SHPS1 and BIT) is a variably glycosylated 90-120 kDa member of the SIRP family of proteins.  It is widely expressed, being found on neurons, microglia/macrophages, endothelium, and fibroblasts.  SIRP alpha has a variety of functions, including presynsptic organization, inhibition of integrin action, and induction of myogenesis.  It binds to CD47 and likely other ligands.  Mature human SIRP alpha is a 477 amino acid (aa) type I transmembrane glycoprotein.  It contains an extracellular region (aa 27-372) that shows one V-type Ig-like (aa 32-137) and two C2-type Ig-like domains (aa 147-347).  Its cytoplasmic domain possesses two ITIMs which interact with protein tyrosine phosphatases.  There is one alternative start site at Met102 plus a four aa insertion after Gln421.  Over aa 27-370, human SIRP alpha shares 61% aa identity with mouse SIRP alpha.
