Anti-Signal-regulatory protein alpha Antibody, Non-Fucosylated (BioBet-1287ZP) (CAT#: BioBet-1287ZP) Datasheet

SIRPA

signal-regulatory protein alpha

The protein encoded by this gene is a member of the signal-regulatory-protein (SIRP) family, and also belongs to the immunoglobulin superfamily. SIRP family members are receptor-type transmembrane glycoproteins known to be involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. This protein can be phosphorylated by tyrosine kinases. The phospho-tyrosine residues of this PTP have been shown to recruit SH2 domain containing tyrosine phosphatases (PTP), and serve as substrates of PTPs. This protein was found to participate in signal transduction mediated by various growth factor receptors. CD47 has been demonstrated to be a ligand for this receptor protein. This gene and its product share very high similarity with several other members of the SIRP family. These related genes are located in close proximity to each other on chromosome 20p13. Multiple alternatively spliced transcript variants have been determined for this gene.

Diseases associated with SIRPA include Suppression Amblyopia and Bladder Neck Obstruction.

Its related pathways are Cell surface interactions at the vascular wall and Tyrosine Kinases / Adaptors.

CD47 immunoglobulin-like cell surface receptor. As a docking protein, it induces the translocation of binding substances such as PTPN6 and PTPN11 from the cytoplasm to the plasma membrane. Supports the adhesion of cerebellar neurons, the growth of neurites and the adhesion of glial cells. May play a key role (through similarity) in intracellular signaling of synapse occurrence and synaptic function. Participate in the negative regulation of cell adhesion, growth factor or insulin-induced receptor tyrosine kinase coupled cell response. Mediates the negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 binding can prevent the maturation of immature dendritic cells and inhibit the production of cytokines by mature dendritic cells.
