ARHGAP20 (Rho GTPase Activating Protein 20) is a Protein Coding gene. Diseases associated with ARHGAP20 include Chronic Lymphocytic Leukemia. Among its related pathways are p75 NTR receptor-mediated signalling and Signaling by Rho GTPases. The protein encoded by ARHGAP20 is an activator of RHO-type GTPases, transducing a signal from RAP1 to RHO and impacting neurite outgrowth.
