WebApr 13, 2024 · We first focused on membrane-associated proteins BRO1-like, Arf GTPase, and Rab GTPase, which have been predicted to undergo MYR. We identified six BRO1-like proteins. BRO1 is an endosome-associated protein initially identified in yeasts that functions in multivesicular body (MVB) formation and vacuolar protein sorting (Odorizzi et al. 2003). 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) …

The GAP of ARD1 stimulates GTPase hydrolysis for ARD1 but not ARFs. 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. fishing trawler afk guide

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. 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 ).

WebSep 15, 2024 · Arf GTPase-Activating proteins (ArfGAPs) mediate the hydrolysis of GTP bound to ADP-ribosylation factors (Arfs), which are critical to form transport intermediates. ArfGAPs have been thought to be negative regulators of Arfs; however, accumulating evidence indicates that ArfGAPs are important for cargo sorting and promote membrane … WebNov 15, 2024 · Instead, flowering plants express plant-specific putative ARF GTPases such as ARFA and ARFB, in addition to evolutionarily conserved ARF-LIKE (ARL) proteins. Here we show that all eight ARF-GEFs of Arabidopsis interact with the same ARF1 GTPase, whereas only a subset of post-Golgi ARF-GEFs also interacts with ARFA, as assayed by …
