Function
ABL2 is a cytoplasmic
tyrosine kinase
A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell. It functions as an "on" or "off" switch in many cellular functions.
Tyrosine kinases belong to a larger cl ...
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 expression of ABL2 gene is higher in KRAS mutant non-small cell lung cancer.
The ABL2 gene product is expressed as two variants bearing different amino termini, both approximately 12-kb in length.
Interactions
ABL2 has been shown to
interact with three proteins:
Abl gene
Tyrosine-protein kinase ABL1 also known as ABL1 is a protein that, in humans, is encoded by the ''ABL1'' gene (previous symbol ''ABL'') located on chromosome 9. c-Abl is sometimes used to refer to the version of the gene found within the mammalia ...

catalase
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting t ...

SORBS2.
The protein Abl gene is also known as abelson murine leukemia viral oncogene homolog 1 and is a protein that is encoded by the human ABL1 gene.

Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...

Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3% ...

gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...
