Is predicted to encode a protein with the following domains: Abl-interactor HHR; Abl-interactor, homeo-domain homologous domain; ABI gene family member 3; and ABI family. 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.
