Putative gtpase activating protein for arf
WebArfs are a family of Ras-related GTP-binding proteins that function in the regulation of ... (GTPase-activating proteins) function with which Arf proteins. Although in vitro assays may indicate Arf preferences for the numerous Arf GEFs and GAPs ... Whereas Arf6 is targeted to the plasma membrane through multiple regions along the protein, ... WebPA stimulates Arf-GTPase-activating proteins (Arf-GAPs), which are involved in membrane trafficking events and actin cytoskeletal function. To determine if Spo14p-generated PA mediates its biological response through Arf-GAPs, we analyzed the sporulation efficiencies of cells deleted for each of the five known and potential yeast Arf-GAPs.

WebGTPase-Activating Proteins. GAPs act by binding to the GTPase and enhancing hydrolysis of GTP, an otherwise slow and inefficient process, and by promoting the conversion of GTP to GDP they are negative regulators of Rho GTPases ( Moon and Zheng, 2003; Tcherkezian and Lamarche-Vane, 2007 ). Rho GAPs share in common a 140-amino-acid domain ... Webdisrupted GTPase-activating protein activity, had a reduced effect on cell spreading and increased the number of cells forming dorsal ruffles in response to PDGF. These data support a role for an Arf GTPase-activating protein, ASAP1, as a regulator of cytoskeletal remodeling and raise the possibility that the Arf pathway is a target for PDGF ...
WebAbstract. Regulators of Arf activity include a family of proteins with a shared domain, the cysteine-rich Arf GAP domain, that is responsible for activating the latent GTPase activity of Arfs. The first of these to be discovered, Arf GAP1 is the focus of this chapter.
WebADP-ribosylation factors (Arfs) and Arf GTPase-activating proteins (GAPs) are key regulators of membrane trafficking and the actin cytoskeleton. The Arf GAP ASAP1 contains an N-terminal BAR domain, which can induce membrane tubulation. Here, we report that the BAR domain of ASAP1 can also function as a protein binding site. WebADP-ribosylation factors (Arfs) and Arf-like (Arl) GTPases are key regulators of intracellular vesicle trafficking and Golgi structure. Both Arf and Arl proteins cycle between active GTP-bound and inactive GDP-bound forms, where guanine nucleotide exchange factors (GEFs) regulate the exchange of GDP for GTP, whereas GTPase-activating proteins (GAPs) …
