Entrez Gene Number
Entrez Gene SummaryThis gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P21860 # Binds and is activated by neuregulins and NTAK.
SIZE: 1342 amino acids; 148098 Da
SUBUNIT: Heterodimer with each of the other ERBB receptors (Potential). Interacts with CSPG5 and PA2G4.
SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Single-pass type I membrane protein. & Isoform 2: Secreted.
TISSUE SPECIFICITY: Epithelial tissues and brain.
DOMAIN: SwissProt: P21860 The cytoplasmic part of the receptor may interact with the SH2 or SH3 domains of many signal-transducing proteins.
PTM: Ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (By similarity).
DISEASE: SwissProt: P21860 # Overexpressed in a subset of human mammary tumors. & Defects in ERBB3 are the cause of lethal congenital contracture syndrome type 2 (LCCS2) [MIM:607598]; also called Israeli Bedouin multiple contracture syndrome type A. LCCS2 is an autosomal recessive neurogenic form of a neonatally lethal arthrogryposis that is associated with atrophy of the anterior horn of the spinal cord. The LCCS2 syndrome is characterized by multiple joint contractures, anterior horn atrophy in the spinal cord, and a unique feature of a markedly distended urinary bladder. The phenotype suggests a spinal cord neuropathic etiology.
SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily. & Contains 1 protein kinase domain.
