Ankyrin Repeat and GTPase Domain Arf GTPase Activating Protein 11, or, AGAP11, is a human gene. Other names include: Arf-GAP with GTPase, ANK repeat and PH domain-containing protein 11; AGAP-11; Centaurin-gamma-like protein KIAA1975; ankyrin repeat and GTPase domain Arf GTPase activating protein 11. The encoded protein has an amino acid length of 550 and a mass of 60.5 kDa. Other isoforms may exist. Ankyrin Repeat and GTPase Domain Arf GTPase Activating Protein 11 is a member of the Centaurin gamma-like family.
