MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the Tyr protein kinase family and the epidermal growth factor receptor subfamily. It encodes a single-pass type I membrane protein with multiple cysteine rich domains, a transmembrane domain, 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 and other factors and 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. Mutations in this gene have been associated with cancer. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit cardiac defects, alterations in hindbrain development, and midgestational lethality. Heterozygotes show schizophrenia-like behavior. Genetically rescued females show mammary defects. [provided by MGI curators]

Protein Function and Prediction

Erbb4 encodes a type I tyrosine kinase receptor of the epidermal growth factor receptor (EGFR) family (1). Erbb4 interacts with PSD95 and is proposed to be involved in synaptic plasticity (2;3).  Erbb4 has been implicated in initiating anti-proliferative and pro-differentiation signals [(4); reviewed in (5)].  Betacellulin and epiregulin as well as neuregulin-1, -3, and -4 are ligands of Erbb4 (6;7).

Expression/Localization

Northern blot analysis of human tissues found that the highest expression of ERBB4 was in the heart and skeletal muscle (1).  Another transcript was highly expressed in the brain, with lower levels in the heart, skeletal muscle, kidney, and pancreas (1). Erbb4 is expressed ubiquitously throughout adult and fetal mouse tissues.  Strongest expression is in the lining epithelia of the gastrointestinal, urinary, reproductive, and respiratory tracts, as well as in skin, skeletal muscle, circulatory, endocrine, and nervous systems. The developing brain and heart expressed high levels of Erbb4 (8).

Background

Erbb4tm1Grl/tm1Grl; MGI:1929607

involves: 129S1/Sv * 129X1/SvJ * C57BL/6J

Homozygotes for a targeted null mutation exhibit cardiac defects, alterations in hindbrain development, abnormal motor and sensory neuron innervation, and midgestational lethality (9). Heterozygotes show schizophrenia-like behavior (9). Genetically rescued females show mammary defects (9).
