Predicted to enable non-membrane spanning protein tyrosine kinase activity. Involved in several processes, including defense response to other organism; negative regulation of DNA damage response, signal transduction by
p53 class mediator; and negative regulation of engulfment of apoptotic cell. Predicted to be located in cytoplasm and plasma membrane. Expressed in Q cell; germ cell; neurons; pharynx; and ventral nerve cord. Human ortholog(s) of this gene implicated in several diseases, including gastrointestinal system cancer (multiple); leukemia (multiple); and lung non-small cell carcinoma. Is an ortholog of human ABL1 (ABL proto-oncogene 1, non-receptor tyrosine kinase) and ABL2 (ABL proto-oncogene 2, non-receptor tyrosine kinase).
