ALK Gene

anaplastic lymphoma receptor tyrosine kinase

This gene encodes a receptor tyrosine kinase, which belongs to the insulin receptor superfamily. This protein comprises an extracellular domain, an hydrophobic stretch corresponding to a single pass transmembrane region, and an intracellular kinase domain. It plays an important role in the development of the brain and exerts its effects on specific neurons in the nervous system. This gene has been found to be rearranged, mutated, or amplified in a series of tumours including anaplastic large cell lymphomas, neuroblastoma, and non-small cell lung cancer. The chromosomal rearrangements are the most common genetic alterations in this gene, which result in creation of multiple fusion genes in tumourigenesis, including ALK (chromosome 2)/EML4 (chromosome 2), ALK/RANBP2 (chromosome 2), ALK/ATIC (chromosome 2), ALK/TFG (chromosome 3), ALK/NPM1 (chromosome 5), ALK/SQSTM1 (chromosome 5), ALK/KIF5B (chromosome 10), ALK/CLTC (chromosome 17), ALK/TPM4 (chromosome 19), and ALK/MSN (chromosome X).[provided by RefSeq, Jan 2011]

ALKAL1 Gene

ALK and LTK ligand 1

Enables protein tyrosine kinase activator activity and signaling receptor binding activity. Involved in cell surface receptor protein tyrosine kinase signaling pathway; positive regulation of MAPK cascade; and positive regulation of neuron projection development. Is active in extracellular space. [provided by Alliance of Genome Resources, Mar 2025]

ALKAL2 Gene

ALK and LTK ligand 2

Enables protein tyrosine kinase activator activity and signaling receptor binding activity. Involved in cell surface receptor protein tyrosine kinase signaling pathway; positive regulation of MAPK cascade; and positive regulation of neuron projection development. Is active in extracellular space. [provided by Alliance of Genome Resources, Mar 2025]
