Enables several functions, including ATP binding activity; metal ion binding activity; and signaling receptor binding activity. Involved in several processes, including negative regulation of long-term synaptic potentiation; positive regulation of blood vessel branching; and positive regulation of cell migration involved in sprouting angiogenesis. Acts upstream of or within several processes, including cell surface receptor signaling pathway; hematopoietic or lymphoid organ development; and regulation of signal transduction. Located in several cellular components, including actin cytoskeleton; cell leading edge; and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and sensory organ. Human ortholog(s) of this gene implicated in gastrointestinal system cancer (multiple); leukemia (multiple); and lung non-small cell carcinoma. Orthologous to human ABL1 (ABL proto-oncogene 1, non-receptor tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
