EphB2 Protein, Human (Active, sf9, His-GST)

EphB2 protein is a receptor tyrosine kinase that participates in bidirectional signaling with the transmembrane ephrin B ligand. It guides commissural axons in the developing cerebral cortex, efferent growth cones of the inner ear, and retinal ganglion cell axons. EphB2 Protein, Human (sf9, His-GST) is the recombinant human-derived EphB2 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.

EphB2 protein is a receptor tyrosine kinase that interacts with transmembrane ephrin-B ligands on neighboring cells, resulting in bidirectional signaling. The pathway downstream of EphB2 is known as forward signaling, while the pathway downstream of ephrin ligands is referred to as reverse signaling. EphB2 plays a crucial role in axon guidance during development, particularly in the guidance of commissural axons connecting the temporal lobes of the cerebral cortex, as well as the guidance of inner ear efferent growth cones and retinal ganglion cell axons. It also regulates the development and maturation of dendritic spines and promotes the formation of excitatory synapses, counteracting the negative regulation mediated by ARHGEF15 upon activation by EFNB1. Furthermore, EphB2 is involved in various developmental processes, including angiogenesis, palate development, and endolymph production in the inner ear. Its complex with EFNB2 controls cell movement and adhesion during the tubularization of the urethra and septation of the cloaca. Additionally, EphB2 may have tumor suppressor activity and could influence platelet activation and blood coagulation.
