ABL1 Gene

The gene ABL1 also called "Abelson Murine Leukemia Viral Oncogene Homolog 1" is a protooncogene located on the long arm of chromosome 9 (9q34.1) and has 12 exons. It encodes a tyrosine kinase, which is physiologically involved in various cellular processes. Tyrosine kinase participates in cell division, cell adhesion, cell differentiation and cellular stress response. The tyrosine kinase activity of the gene product can be negatively regulated by its SH3 domain. Deletion of the region encoding the SH3 domain leads to the formation of an oncogene and consequently a constitutively active tyrosine kinase. The DNA-binding activity of the encoded protein is regulated by CDC2-mediated phosphorylation. The ABL1 gene is involved in the development of various leukemias.
