| Short Description: |
Recombinant-Mouse SIRP alpha-protein was developed from hek293. For use in research applications. |
| Conjugation: |
Unconjugated |
| Formulation: |
Lyophilised from 0.2 Mu m filtered PBS solution, pH7.2, 5% Trehalose. |
| Dilution Range: |
Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers. |
| Storage Instruction: |
Can be stored in working aliquots at 2°C-8°C C for one month, or at-20°C to-70°C for 1 year. Avoid repeated freeze/thaw cycles. NA |
| Endotoxin: |
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA |
| Immunoreactivity: |
The activity was determined by the ability of immobilized mouse SIRPA to bind recombinant human CD47. The ED50 was calculated to be NA |
| Gene Symbol: |
Sirpa |
| Gene ID: |

| Uniprot ID: |
SHPS1_MOUSE |
| Immunogen Region: |
THR32-Asn 373 |
| Immunogen: |
Optimized DNA sequence encodingMouse Signal regulatory protein alpha-SIRP alpha (SHPS1) (THR32-Asn 373) extracellular domain including a C-terminal His tag was expressed in HEK293 cells. NA |
| Tissue Specificity | 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. Detected in neurons of the hippocampus and dentate gyrus, and in olfactory bulb. Not detected in Purkinje cells. Highly expressed in the plexiform layers, optic fiber layer and the outer segments of the photoreceptor layer in the retina. Highly expressed in macrophages. Isoform 3 is detected at very low levels in all tissues tested. |
| Post Translational Modifications | N-glycosylated. Phosphorylated on tyrosine residues. |
| Function | Immunoglobulin-like cell surface receptor for CD47. Acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. Supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. May play a key role in intracellular signaling during synaptogenesis and in synaptic function. Involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. Mediates 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. Plays a role in antiviral immunity and limits new world arenavirus infection by decreasing virus internalization. Receptor for THBS1. Interaction with THBS1 stimulates phosphorylation of SIRPA. In response to THBS1, involved in ROS signaling in non-phagocytic cells, stimulating NADPH oxidase-derived ROS production. |
