Tyrosine-protein kinase ABL2 also known as Abelson-related gene (Arg) is an enzyme that in humans is encoded by the ABL2 gene.[1][2]


ABL2 is a cytoplasmic tyrosine kinase which is closely related to but distinct from ABL1. The similarity of the proteins includes the tyrosine kinase domains and extends amino-terminal to include the SH2 and SH3 domains. ABL2 is expressed in both normal and tumor cells. The ABL2 gene product is expressed as two variants bearing different amino termini, both approximately 12-kb in length.[2]


ABL2 has been shown to interact with:
