功能Direct ligand for the ERBB4 tyrosine kinase receptor. Binding results in ligand-stimulated tyrosine phosphorylation and activation of the receptor. Does not bind to the EGF receptor, ERBB2 or ERBB3 receptors. May be a survival factor for oligodendrocytes.
组织特异性Highly expressed in most regions of the brain with the exception of corpus callosum. Expressed at lower level in testis. Not detected in heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, ovary, small intestine, colon and peripheral blood leukocytes.
序列相似性Belongs to the neuregulin family. Contains 1 EGF-like domain.
发展阶段Isoform 3 is expressed in fetal brain but not in other fetal tissues.
结构域The cytoplasmic domain may be involved in the regulation of trafficking and proteolytic processing. Regulation of the proteolytic processing involves initial intracellular domain dimerization. ERBB receptor binding is elicited entirely by the EGF-like domain.
翻译后修饰Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form. Extensive glycosylation precedes the proteolytic cleavage (By similarity). Isoform 3 is glycosylated.
细胞定位Secreted; Cell membrane. Does not seem to be active and Cell membrane. Isoform 3 is also proteolytically released as a soluble form.
