Enables SH3 domain binding activity and protein kinase binding activity. Involved in several processes, including positive regulation of endocytosis; presynaptic actin cytoskeleton organization; and synaptic vesicle clustering. Located in axon; cytoplasm; and somatodendritic compartment. Expressed in coelomocyte; head neurons; and ventral cord neurons. Is an ortholog of human ABI1 (abl interactor 1).
Predicted to enable actin filament binding activity. Involved in several processes, including backward locomotion; positive regulation of locomotion; and reproductive behavior. Located in cytoplasm. Expressed in several structures, including excretory cell; hermaphrodite distal tip cell; neurons; non-striated muscle; and socket cell. Human ortholog(s) of this gene implicated in opiate dependence. Is an ortholog of human NAV1 (neuron navigator 1).
