NCIt synonyms : c-erbB-4; ERBB4 Receptor Protein Tyrosine Kinase; erbB4;
NCIt definition : Receptor tyrosine-protein kinase erbB-4 (1308 aa, 147 kDa) is encoded by the human
ERBB4 gene. This protein is involved in multicellular organismal development, cell
proliferation and signal transduction.;
NCIt note : ErbB4 heterodimerizes with other type I receptor tyrosine kinases. In the peripheral
nervous system, ErbB4 helps regulate glial proliferation and acts as a signaling molecule
at the neuromuscular junction. In the mature CNS, ErbB4 is expressed in cerebellar
granule cells and in a subset of cells that also express the neurotransmitter: aminobutyric
acid. ErbB4 is critical in cardiac development. It is overexpressed frequently in
several common solid tumors, including in breast cancer.;
