Immunohistochemistry (IHC)
(MBS9607922 at 1/100 staining Mouse brain tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)

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.
Subunit Structure: Monomer. Homodimer. Forms heterodimers with EPHA2. Binds to the receptor tyrosine kinases EPHA2, EPHA3, EPHA4, EPHA5, EPHA6 and EPHA7. Also binds with low affinity to EPHA1.
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.
Similarity: Belongs to the ephrin family.
NCBI and Uniprot Product Information
Predicted: 24 kDa
NCBI Description
This gene encodes a member of the ephrin (EPH) family. The ephrins and EPH-related receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. This gene encodes an EFNA class ephrin which binds to the EPHA2, EPHA4, EPHA5, EPHA6, and EPHA7 receptors. Two transcript variants that encode different isoforms were identified through sequence analysis. [provided by RefSeq, Jul 2008]

Product Notes
The EFNA1 efna1 (Catalog #AAA9607922) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The EFNA1 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's EFNA1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemisty (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (EIA). WB: 1:500-1:2000 IHC: 1:50-1:200 IF/ICC: 1:100-1:500. Researchers should empirically determine the suitability of the EFNA1 efna1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "EFNA1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
