NCBI Description of ARHGAP21

ARHGAP21 functions preferentially as a GTPase-activating protein (GAP) for CDC42 (MIM 116952) and regulates the ARP2/3 complex (MIM 604221) and F-actin dynamics at the Golgi through control of CDC42 activity (Dubois et al., 2005 [PubMed 15793564]).[supplied by OMIM, Mar 2008]. Sequence Note: The 5'-most in-frame translation start codon is selected for this RefSeq and is well-conserved among mammalian species. An alternative start codon that would reduce the protein length by 1 aa is also present. The use of the downstream start codon is assumed in the literature, including PMIDs:12056806, 15793564 and 17347647.
