InnateDB Gene

IDBG-48049 (NRG2)

Protein Structure

UniProt Annotation

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.

Subcellular Localization

Pro-neuregulin-2, membrane-bound isoform: Cell membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Note=Does not seem to be active. {ECO:0000250}.Neuregulin-2: Secreted {ECO:0000250}.

Disease Associations

Tissue Specificity

Restricted to the cerebellum in the adult.
