ab273118 Anti-Ephrin type-A receptor 2 antibody [EPR24711-11] was shown to specifically react with Ephrin type-A receptor 2 in wild-type HeLa cells. Loss of signal was observed when knockout cell line (ab264795) was used. Wild-type and Ephrin type-A receptor 2 knockout samples were subjected to SDS-PAGE. ab273118 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at 4℃ overnight at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Supplementary information

Eph receptor A2 also known as EphA2 or A2 receptor is a type of protein that functions as a receptor tyrosine kinase. It has an approximate mass of 130 kDa. Researchers find this receptor widely expressed in various tissues including epithelial cells and some neuronal populations. EphA2 is involved in cell positioning movement and organization by interacting with ephrin ligands notably ephrin A1. The receptor-ligand interaction triggers bidirectional signaling that affects cell structure and function.
Biological function summary

Eph receptor A2 participates in important cellular processes such as angiogenesis cell proliferation and migration. It often functions as part of larger signaling networks or complexes that include other Eph receptors and ephrin ligands. These interactions help regulate cell adhesion and detachment which are important for embryonic development and tissue organization. EphA2 studies often use fluorescent labeling strategies such as Alexa 588 to track its expression and activity in cells.

Pathways

Eph receptor A2 integrates into the PI3K/AKT and MAPK signaling pathways which are important for cell survival growth and differentiation. It interacts with proteins like Ras and ERK within these pathways to modulate their functions. EphA2 signaling influences cytoskeletal dynamics and morphogenesis making it an important component in maintaining tissue architecture. Research also indicates a connection between EphA2 and the APC protein highlighting its role in the Wnt signaling pathway.

The Eph receptor A2 shows significant involvement in cancer and inflammatory conditions. Overexpression or dysregulation of EphA2 occurs frequently in various cancers including breast and prostate cancer correlating with increased tumor aggressiveness and metastasis. The receptor also interacts with other proteins such as APC which links to tumorigenesis and cancer progression. In immunology EphA2 plays a part in chronic inflammatory diseases by modulating immune cell migration and vascular inflammation. Understanding these connections provides insights for potential therapeutic targets using molecular interventions like A2 antibodies and APC-based strategies.

Target data

Receptor tyrosine kinase which binds promiscuously membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Activated by the ligand ephrin-A1/EFNA1 regulates migration, integrin-mediated adhesion, proliferation and differentiation of cells. Regulates cell adhesion and differentiation through DSG1/desmoglein-1 and inhibition of the ERK1/ERK2 (MAPK3/MAPK1, respectively) signaling pathway. May also participate in UV radiation-induced apoptosis and have a ligand-independent stimulatory effect on chemotactic cell migration. During development, may function in distinctive aspects of pattern formation and subsequently in development of several fetal tissues. Involved for instance in angiogenesis, in early hindbrain development and epithelial proliferation and branching morphogenesis during mammary gland development. Engaged by the ligand ephrin-A5/EFNA5 may regulate lens fiber cells shape and interactions and be important for lens transparency development and maintenance. With ephrin-A2/EFNA2 may play a role in bone remodeling through regulation of osteoclastogenesis and osteoblastogenesis.. (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) in hepatocytes and facilitates its cell entry. Mediates HCV entry by promoting the formation of the CD81-CLDN1 receptor complexes that are essential for HCV entry and by enhancing membrane fusion of cells expressing HCV envelope glycoproteins.. Acts as a receptor for human cytomegalovirus (HCMV) to mediate viral entry and fusion in glioblastoma cells.
