EPHB3

Ephrin type-B receptor 3 is a is_associated_with::protein that in humans is encoded by the EPHB3 is_associated_with::gene.

Function
Ephrin receptors and their ligands, the ephrins, mediate numerous developmental processes, particularly in the nervous system. 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. The Eph family of receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. The protein encoded by this gene is a receptor for ephrin-B family members.

Interactions
EPHB3 has been shown to interact with is_associated_with::MLLT4 and is_associated_with::RAS p21 protein activator 1.
