Background: c-Abl

Tyrosine protein kinase ABL1 (Abelson murine leukemia viral oncogene homolog 1) is a ubiquitously expressed, magnesium-dependent, cytosolic member of the ABL subfamily of non-receptor protein tyrosine kinases (1). Human nonreceptor tyrosine kinases share a conserved domain structure that contributes to activity regulation and substrate specificity in many key processes linked to cell growth and survival (2-4). In addition, ABL1 contains domains unique to the ABL1 paralog that enable its function in DNA binding and DNA-damage response. ABL1 is composed of an N-terminal glycine myristoyl group that blocks the surface pocket of the kinase domain, a cap that stabilizes an inactive conformation, SH3 and SH2 domains that impose a locked inactive state, a protein kinase region, three nuclear localization signals, a DNA-binding region, and C-terminal nuclear export signal motifs, and actin F-binding domain (5-9). Activity is regulated through disruption of autoinhibitory interactions and several phosphorylation events that increase or decrease activity or promote function through stabilization (4). The SH2 domain contributes to both catalytic activity and target site specificity as has been shown with domain swapping (10). In chronic myelogenous, acute myeloid, and acute lymphoblastic leukemias, ABL1 is fused to BCR gene, resulting in deletion of the regulatory domains and production of a constitutively active tyrosine kinase (11). Several mutations in ABL1 lead to misregulation of activity in a variety of cancers (12).  ABL1 kinase inhibition is used for therapeutic treatment in leukemic cancers and requires further development of drugs to address ABL1-mutation conferred resistance (12,13).
