Is predicted to encode a protein with the following domains: ABI gene family member 3; ABI family; Abl-interactor HHR; and Abl-interactor, homeo-domain homologous domain. Is an ortholog of C. elegans abi-1. In C. elegans, abi-1 is involved in several processes, including positive regulation of endocytosis; presynaptic actin cytoskeleton organization; and synaptic vesicle clustering.
