ArfGAP With GTPase, ANK Repeat And PH Domain Containing Protein 9 (AGAP9)

CTGLF6; Centaurin Gamma Like Family Member 6

ArfGAP With GTPase, ANK Repeat And PH Domain Containing Protein 9 (AGAP9)
AGAP9 Belongs to the centaurin gamma-like family.Contains 1 ANK repeat.Contains 1 Arf-GAP domain.Contains 1 PH domain.Centaurins are a family of proteins that contain GTPase-activating protein domains, with the gamma family members containing in addition a GTPase-like domain. Centaurins reside mainly in the nucleus and are known to activate phosphoinositide 3-kinase, a key regulator of cell proliferation, motility and vesicular trafficking. In the present study, using X-ray structural analysis, enzymatic assays and nucleotide-binding studies,for CENTG1 (centaurin gamma-1) the GTPase-like domain has broader trinucleotide specificity. Alterations within the G4 motif of CENTG1 from the highly conserved NKXD found in typical GTPases to TQDR result in the loss of specificity, a lower affinity for the nucleotides and higher turnover rates.
