a tyrosine kinase of the ALK family. Plays an important role in the development of the brain and exerts its effects on specific neurons in the nervous system. Translocated and expressed as a fusion protein in anaplastic lymphoma. About one third of large-cell lymphomas are caused by a t(2;5)(p23;q35) translocation that fuses ALK to nucleophosmin (NPM1A). Other cases caused by fusions of ALK to moesin, non-muscle myosin heavy chain 9, clathrin heavy chain and other genes. Several fusions also seen in inflammatory myofibroblastic tumors, and expression has been briefly noted in a range of tumors Note: This description may include information from UniProtKB.
