Summary
ARHGAP1 (Rho GTPase activating protein 1, HGNC:673) is a protein-coding gene on chromosome 11p11.2, encoding Rho GTPase-activating protein 1 (Q07960). GTPase activator for the Rho, Rac and Cdc42 proteins, converting them to the putatively inactive GDP-bound state.
This gene encodes a member of a large family of proteins that activate Rho-type guanosine triphosphate (GTP) metabolizing enzymes. The encoded protein contains a SRC homology 3 domain and interacts with Bcl-2-associated protein family members.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 135 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
