CD172a, also known as SIRPA (signal regulatory protein alpha), SHPS-1 (SHP substrate 1) and MyD-1 (Myeloid/Dendritic-1), is single pass type I transmembrane glycoprotein that belongs to the SIRP/SHPS (CD172) family of the immunoglobulin (Ig) superfamily. CD172a contains 1 Ig-like V-type and 2 Ig-like C1-type domains in the extracellular region and a cytoplasmic tail with ITIM motifs that recruit tyrosine phosphatases SHP-1 and SHP-2 when phosphorylated. CD172a is involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes induced by cell adhesion, growth factors or insulin. CD172a is expressed mainly on myeloid cells, including macrophages, neutrophils, dendritic and Langerhans cells. It is also found on neurons, smooth muscle and endothelial cells. CD172a participates in signal transduction mediated by various growth factor receptors. CD172a supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. CD172a mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 has been demonstrated to be a ligand for CD172a. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. The CD47 integrin-CD172a interaction may promote macrophage fusion during osteoclastogenesis.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
