Predicted to enable GTPase activity and polyubiquitin modification-dependent protein binding activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within cellular response to reactive oxygen species and protein import into nucleus. Predicted to be located in cell periphery and cytoplasm. Predicted to be active in nucleus. Orthologous to human AGAP3 (ArfGAP with GTPase domain, ankyrin repeat and PH domain 3). [provided by Alliance of Genome Resources, Apr 2022]
