uniprot
proteins
function
FUNCTION: Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. May also promote the heterodimerization with the EGF receptor. {ECO:0000269|PubMed:9168115}.

post_translational_modification
PTM: Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form. {ECO:0000250}.; PTM: Extensive glycosylation precedes the proteolytic cleavage. {ECO:0000250}.
