an ubiquitously expressed and highly conserved proto-oncogenic, non-receptor tyrosine kinase. Shuttles between the nucleus and the cytoplasm, where it localizes to the cytosol, endoplasmic reticulum, and mitochondria. Negatively regulated by its SH3 domain, and deletion of the SH3 domain turns ABL1 into an oncogene. It has been implicated in regulation of cell proliferation, differentiation, apoptosis, cell adhesion and stress response. The Philadephia chromosome translocation t(9;22)(q34;q11) creates a Bcr-Abl fusion protein, responsible for 90% of chronic myelogenous leukemia (CML) and ~25% of acute lymphoblastic leukemia (ALL). Is inhibited by active-site binding small molecules such as imatinib (Gleevec), Dasatinib, Nilotinib, Bosutinib, Ponatinib, and Bafetinib. Compounds such as GNF-2 that bind the myristate-binding pocket of Abl allosterically inhibit Abl kinase activity. Two alternatively-spliced human isoforms have been described: one that is N-terminally myristoylated and the other not due to an alternative splicing of the first exon.
