Receptor tyrosine-protein kinase erbB-4 is an enzyme that in humans is encoded by the ERBB4 gene.[1][2] Alternatively spliced variants that encode different protein isoforms have been described; however, not all variants have been fully characterized.[3]

Function[edit]

Receptor tyrosine-protein kinase erbB-4 is a receptor tyrosine kinase that is a member of the epidermal growth factor receptor subfamily. ERBB4 is a single-pass type I transmembrane protein with multiple furin-like cysteine rich domains, a tyrosine kinase domain, a phosphotidylinositol-3 kinase binding site and a PDZ domain binding motif. The protein binds to and is activated by neuregulins-2 and -3, heparin-binding EGF-like growth factor and betacellulin. Ligand binding induces a variety of cellular responses including mitogenesis and differentiation. Multiple proteolytic events allow for the release of a cytoplasmic fragment and an extracellular fragment.[3]

Clinical significance[edit]

Mutations in this gene have been associated with cancer.[3] Other single-nucleotide polymorphisms and a risk haplotype have been linked to schizophrenia.[4] Single-nucleotide polymorphisms in ERBB4 have also been found in a study of patients with familial Amyotrophic lateral sclerosis type 19 [5]

Interactions[edit]

ERBB4 has been shown to interact with:
