  • Function
    Receptor for members of the ephrin-B family. Phosphorylates ARHGEF15, leading to its ubiquitination and degradation by the proteasome which promotes EFNB1-dependent synapse formation. Can function in aspects of retinal ganglion cell axon guidance to the optic disk even when lacking its tyrosine kinase domain. Acts as a tumor suppressor.
  • Tissue specificity
    Brain, heart, lung, kidney, placenta, pancreas, liver and skeletal muscle. Preferentially expressed in fetal brain.
  • Involvement in disease
    Defects in EPHB2 may be a cause of susceptibility to prostate cancer (PC) [MIM:176807]. It is a malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet-ring cell carcinoma and neuroendocrine carcinoma. Note=EPHB2 mutations have been found in a prostate cancer cell line derived from a brain metastasis.
  • Sequence similarities
    Belongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 1 protein kinase domain.
    Contains 1 SAM (sterile alpha motif) domain.
