Predicted to enable metal ion binding activity; phosphotyrosine residue binding activity; and protein tyrosine kinase activity. Predicted to be involved in several processes, including cellular response to retinoic acid; peptidyl-tyrosine phosphorylation; and synapse maturation. Predicted to act upstream of or within several processes, including nervous system development; regulation of signal transduction; and transmembrane receptor protein tyrosine kinase signaling pathway. Predicted to be located in several cellular components, including dendritic spine; lamellipodium; and phagocytic cup. Predicted to be active in glutamatergic synapse. Orthologous to human ABL2 (ABL proto-oncogene 2, non-receptor tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
