Ephb1 Gene Summary [Rat]
Enables protein tyrosine kinase activity. Involved in hindbrain tangential cell migration and protein autophosphorylation. Acts upstream of or within dendritic spine development and immunological synapse formation. Predicted to be located in several cellular components, including early endosome membrane; filopodium tip; and membrane raft. Predicted to be active in dendrite; glutamatergic synapse; and plasma membrane. Biomarker of myocardial infarction. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to human EPHB1 (EPH receptor B1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ephb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
