Summary: Predicted to enable GTPase activator activity. Predicted to be involved in several processes, including regulation of actin filament polymerization; regulation of small GTPase mediated signal transduction; and small GTPase mediated signal transduction. Predicted to be located in several cellular components, including cytoplasmic microtubule; nuclear speck; and ruffle. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in schizophrenia. Orthologous to human ARHGAP18 (Rho GTPase activating protein 18). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
