EphA3 Protein, Rat (HEK293, His)

The EphA3 protein is a receptor tyrosine kinase that promiscuously binds to membrane-bound ephrin ligands to initiate bidirectional signaling. Activation of EphA3 is known to preferentially bind to EFNA5 and regulates cell-cell adhesion, cytoskeletal organization, and migration. EphA3 Protein, Rat (HEK293, His) is the recombinant rat-derived EphA3 protein, expressed by HEK293 , with C-His labeled tag. The total length of EphA3 Protein, Rat (HEK293, His) is 521 a.a., with molecular weight of ~75-95 kDa.

The EphA3 protein, a receptor tyrosine kinase, engages in promiscuous binding to membrane-bound ephrin family ligands on adjacent cells, initiating contact-dependent bidirectional signaling. The downstream pathway originating from the receptor is known as forward signaling, while the pathway downstream of the ephrin ligand is termed reverse signaling. Highly promiscuous for ephrin-A ligands, EphA3 exhibits a preferential binding affinity for EFNA5. Upon activation by EFNA5, EphA3 plays a pivotal role in regulating cell-cell adhesion, cytoskeletal organization, and cell migration. Additionally, EphA3 is implicated in cardiac cell migration and differentiation, regulating the formation of the atrioventricular canal and septum during development, likely through activation by EFNA1. In the context of retinotectal mapping, EphA3 is involved in the guidance of neurons. Furthermore, EphA3 may control the segregation, though not the guidance, of motor and sensory axons during neuromuscular circuit development.

Measured by its binding ability in a functional ELISA. Immobilized rat EPHA3 at 10 μg/mL (100 μL/well) can bind rat EFNA5, The ED₅₀ for this effect is 155.8 ng/mL.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
