The following GTPase activating proteins (GAPs) were shown to bind RHOG and stimulate its GTPase activity, resulting in GTP to GDP hydrolysis and conversion of the active RHO:GTP complex into the inactive RHO:GDP complex:
ARHGAP35 (Amin et al. 2016; supported by Bagci et al. 2020 by showing binding of ARHGAP35 to the constitutively active RHOG mutant)

The following GAPs were shown to bind RHOG and stimulate its GTPase activity in some but not all studies or were only shown to bind to constitutively active RHOG mutant without testing for the activation of the RHOG GTPase activity and are annotated as candidate RHOG GAPs:
ARHGAP1 (Amin et al. 2016: RHOG directed GAP activity; Bagci et al. 2020: no binding to active RHOG)
ARHGAP5 (Bagci et al. 2020: binding to active RHOG)
ARHGAP21 (Bagci et al. 2020: binding to active RHOG)
ARHGAP32 (Bagci et al. 2020: binding to active RHOG)
ARHGAP39 (Bagci et al. 2020: binding to active RHOG)
DEPDC1B (Bagci et al. 2020: binding to active RHOG)
OPHN1 (Amin et al. 2016: RHOG directed GAP activity; Bagci et al. 2020: no binding to active RHOG)
PIK3R1 (Bagci et al. 2020: binding to active RHOG)

The following GAPs were shown to either not act on RHOG or to not bind the constitutively active RHOG mutant in the high throughput screen by Bagci et al. 2020:
