Human Ephrin-A1/EFNA1 protein (Recombinant) (C-hFc) (STJP002760)
詳情介紹:
Host: | HEK293 cells |
Reactivity: | Human |
Note: | STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
Short Description: | Recombinant-Human Ephrin-A1/EFNA1-C-hFc protein was developed from hek293 cells and has a target region of C-hFc. For use in research applications. |
Formulation: | Lyophilized from a 0.22 Mu m filtered solution of PBS, pH 7.4. |
Storage Instruction: | Store at-20°C for up to 1 year from the date of receipt, and avoid repeat freeze-thaw cycles. |
Immunoreactivity: | Measured by its binding ability in a functional ELISA. Immobilized Human EphA2 at 1 Mu g/mL (100 Mu L/well) can bind Human EFNA1 with a linear range of 0.098-4.084 ng/mL. |
Gene Symbol: | EFNA1 |
Gene ID: | 1942 |
Uniprot ID: | EFNA1_HUMAN |
Immunogen Region: | Asp19-Ser182 |
Immunogen: | Recombinant Human Ephrin-A1/EFNA1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Asp19-Ser182) of human Ephrin-A1/EFNA1 (Accession #NP_004419.2) fused with a hFc tag at the C-terminus. |
Post Translational Modifications | Undergoes proteolysis by a metalloprotease to give rise to a soluble monomeric form. N-Glycosylation is required for binding to EPHA2 receptor and inducing its internalization. |
Function | Cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. Plays an important role in angiogenesis and tumor neovascularization. The recruitment of VAV2, VAV3 and PI3-kinase p85 subunit by phosphorylated EPHA2 is critical for EFNA1-induced RAC1 GTPase activation and vascular endothelial cell migration and assembly. Exerts anti-oncogenic effects in tumor cells through activation and down-regulation of EPHA2. Activates EPHA2 by inducing tyrosine phosphorylation which leads to its internalization and degradation. Acts as a negative regulator in the tumorigenesis of gliomas by down-regulating EPHA2 and FAK. Can evoke collapse of embryonic neuronal growth cone and regulates dendritic spine morphogenesis. |
