General annotation (Comments)

Function

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. Ref.1

Subunit structure

Interacts with ERBB4. Ref.1

Subcellular location

Pro-neuregulin-3, membrane-bound isoform: Cell membrane; Single-pass type I membrane protein By similarity. Note: Does not seem to be active By similarity.

Neuregulin-3: Secreted By similarity.

Tissue specificity

Expressed in sympathetic, motor, and sensory neurons.

Developmental stage

Detected as early as 11 dpc. At 13 dpc detected mainly in the nervous system. At 16 dpc, detected in the brain, spinal cord, trigeminal, vestibular-cochlear, and spinal ganglia. In adults, expressed in spinal cord, and numerous brain regions.

Domain

The cytoplasmic domain may be involved in the regulation of trafficking and proteolytic processing. Regulation of the proteolytic processing involves initial intracellular domain dimerization By similarity.

ERBB receptor binding is elicited entirely by the EGF-like domain By similarity.

Post-translational modification

Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form By similarity.

Extensive glycosylation precedes the proteolytic cleavage By similarity.

Sequence similarities

Belongs to the neuregulin family.

Contains 1 EGF-like domain.
