Receptor tyrosine-protein kinase erbB-4 is an enzyme that in humans is encoded by the ERBB4 gene.^[5][6] Alternatively spliced variants that encode different protein isoforms have been described; however, not all variants have been fully characterized.^[7]

Function

Receptor tyrosine-protein kinase erbB-4 is a receptor tyrosine kinase that is a member of the epidermal growth factor receptor family. 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, -3 and -4, 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.^[7]

Clinical significance

Mutations in this gene have been associated with cancer.^[7] Other single-nucleotide polymorphisms and a risk haplotype have been linked to schizophrenia.^[8] Single-nucleotide polymorphisms in ERBB4 have also been found in a study of patients with familial amyotrophic lateral sclerosis type 19.^[9]

Interactions

ERBB4 has been shown to interact with:

• DLG4^[10][11]
• NRG1,
• STAT5A,^[12][13] and
• YAP1.^[14]
