Opis

Opis ogólny

Tyrosine-protein phosphatase non-receptor type substrate 1 (UniProt: P97797; also known as SHP substrate 1, SHPS-1, Brain Ig-like molecule with tyrosine-based activation motifs, Bit, CD172 antigen-like family member A, Inhibitory receptor SHPS-1, MyD-1 antigen, Signal-regulatory protein alpha-1, Sirp-alpha-1, mSIRP-alpha1, p84, CD172a) is encoded by the Sirpa (also known as Myd1, Ptpns1, Shps1, Sirp) gene (Gene ID: 19261) in murine species. SIRPA is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-31), which is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 32-373), a transmembrane domain (aa 374-394), and a cytoplasmic domain (aa 395-511). Its extracellular region contains one Ig-like V-type domain (aa 32-137) and two Ig-like C1 type domains (aa 149-248 and 255-343). It is highly expressed in cerebral cortex, brain, spinal cord, cerebellum, and spleen, and at much lower levels in kidney, thymus, heart, lung, and liver. Within the cerebellum, highly expressed throughout the molecular layer, and in synaptic glomeruli in the granule cell layer. SIRPA serves as an immunoglobulin-like cell surface receptor for CD47, and their interactions is reported to mediate negative regulation of several monocyte/ macrophage functions. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. SIRPA also acts as a docking protein and induces translocation of PTPN6, PTPN11, and other binding partners from the cytosol to the plasma membrane. SIRPA is phosphorylated on tyrosine residues in response to stimulation with EGF, growth hormone, insulin, and platelet derived growth factor. It is also reported to mediate negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. Four isoforms of SIRPA have been described that are produced by alternative splicing. (Ref.: Sakamoto, M., et al. (2022). Proc. Natl. Acad. Sci. USA. 119(1); e2109923118; Yanagita, T., et al. (2017).
