Protein names

Receptor tyrosine-protein kinase erbB-3 , Proto-oncogene-like protein c-ErbB-3 , Tyrosine kinase-type cell surface receptor HER3

Protein function

Binds and is activated by neuregulins and NTAK. May also be activated by CSPG5. / ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Protein tissue specificity

Epithelial tissues and brain.

Involvement in disease

Lethal congenital contracture syndrome 2 (LCCS2) [MIM:607598]: A form of lethal congenital contracture syndrome, an autosomal recessive disorder characterized by degeneration of anterior horn neurons, extreme skeletal muscle atrophy, and congenital non-progressive joint contractures (arthrogryposis). The contractures can involve the upper or lower limbs and/or the vertebral column, leading to various degrees of flexion or extension limitations evident at birth. LCCS2 patients manifest craniofacial/ocular findings, lack of hydrops, multiple pterygia, and fractures, as well as a normal duration of pregnancy and a unique feature of a markedly distended urinary bladder (neurogenic bladder defect). The phenotype suggests a spinal cord neuropathic etiology. . Note: The disease is caused by mutations affecting the gene represented in this entry.

Protein sequence and domain

The cytoplasmic part of the receptor may interact with the SH2 or SH3 domains of many signal-transducing proteins. / Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily. / Contains 1 protein kinase domain.

Protein post-translational modifications

Ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (By similarity). Subject to autophosphorylation.

Protein cellular localization

Cell membrane; Single-pass type I membrane protein / Secreted
