GenAge entry for ARHGAP1 (Homo sapiens)

Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism

Gene name (HAGRID: 249)

HGNC symbol: ARHGAP1
Aliases: RhoGAP; p50rhoGAP; CDC42GAP; Cdc42GAP
Common name: Rho GTPase activating protein 1

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism
Description: ARHGAP1 a GTPase activator of several proteins. In effect, it acts as a negative regulator of CDC42. Gene targeting of ARHGAP1 in mice results in a short lifespan of about 12 months and the development of multiple premature ageing-like phenotypes, suggesting that this gene may play a role in mammalian ageing [1840].
