Overview 
Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins and EGF family members and regulates development of the heart, the central nervous system and the mammary gland, gene transcription, cell proliferation, differentiation, migration and apoptosis. Required for normal cardiac muscle differentiation during embryonic development, and for postnatal cardiomyocyte proliferation. Required for normal development of the embryonic central nervous system, especially for normal neural crest cell migration and normal axon guidance. Required for mammary gland differentiation, induction of milk proteins and lactation. Acts as cell-surface receptor for the neuregulins NRG1, NRG2, NRG3 and NRG4 and the EGF family members BTC, EREG and HBEGF. Ligand binding triggers receptor dimerization and autophosphorylation at specific tyrosine residues that then serve as binding sites for scaffold proteins and effectors. Ligand specificity and signaling is modulated by alternative splicing, proteolytic processing, and by the formation of heterodimers with other ERBB family members, thereby creating multiple combinations of intracellular phosphotyrosines that trigger ligand- and context-specific cellular responses. Mediates phosphorylation of SHC1 and activation of the MAP kinases MAPK1/ERK2 and MAPK3/ERK1.

Caution 
Conflicting reports about the role of ERBB4 in mediating apoptosis, differentiation, or tumor cell proliferation may be explained by the opposite functions of the different isoforms and their intracellular fragments, and by the formation of heterodimers with other EGF receptor family members (PubMed:18454307 and PubMed:21811097). Thus, heterodimer formation of a kinase-dead ERBB4 mutant with ERBB2 is sufficient for the activation of AKT1, MAPK1/ERK2 and MAPK3/ERK1 (PubMed19098003).
