OverviewNCBI Gene
This gene encodes a member of the Abelson family of nonreceptor tyrosine protein kinases. The protein is highly similar to the c-abl oncogene 1 protein, including the tyrosine kinase, SH2 and SH3 domains, and it plays a role in cytoskeletal rearrangements through its C-terminal F-actin- and microtubule-binding sequences. This gene is expressed in both normal and tumor cells, and is involved in translocation with the ets variant 6 gene in leukemia. Multiple alternatively spliced transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ABL2 as an antibody target. Whether an autoantibody or antibody against ABL2 could matter depends on whether native ABL2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ABL2 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label ABL2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
