Did you know?
WebMature or “late” endosomes are designated by small membrane-bound GTPases Rab7 and Arl8b, which can either operate independently or collaborate to form a joint compartment. Whether, and how, Rab7 and Arl8b resolve this hybrid identity compartment to regain functional autonomy is unknown. Web2 dec. 2014 · The interaction between RILP and HOPS complex is independent of Rab7. (A).

WebThe HOPS complex mediates autophagosome-lysosome fusion through interaction with syntaxin 17. Membrane fusion is generally controlled by Rabs, soluble N-ethylmaleimide … Web30 okt. 2024 · In yeast, but not in mammalian cells, Rab7 directly binds to the accessory subunits Vps39 and Vps41 to recruit HOPS complex to the vacuolar membranes, …
Web2 dec. 2014 · Rab7 and HOPS are structurally conserved in mammalian cells. However, mammalian cells also contain a downstream effector of Rab7 called RILP (Rab … Web22 dec. 2014 · Intriguingly, Rab5 and Rab7 both bind to the hexameric tethering complex HOPS (“homotypic fusion and protein sorting”). Rab5 binds to subunit Vps11 (Rink et al., 2005). Rab7 interacts with subunits Vps39 and Vps41, but SAND1/Mon1 also interacts with Vps39, which in yeast is a Rab7 GEF (Peralta et al., 2010; Plemel et al., 2011).
Web13 jun. 2024 · In metazoan cells including Drosophila, HOPS directly binds to Rab2 and Rab7-binding adaptors to ensure fusions of lysosomes with autophagosomes, late endosomes, secretory granules and Golgi derived vesicles ( Angers and Merz, 2009; Balderhaar and Ungermann, 2013; Csizmadia et al., 2024; Fujita et al., 2024; Jiang et …
Web8 jan. 2015 · HOPS complex subunit Vps39 additionally functions as a GDP exchange factor for Rab7, thus increasing the pools of active Rab7 at the endosomal membrane (Wurmser et al., 2000). Notably, while RILP and HOPS are known to regulate endosome-lysosome fusion, Rab7 regulates the terminal autophagosome-lysosome fusion step ( Gutierrez et … dr mark burhenne dentist mouth tapingWebAs an effector of Rab7/Ypt7, the homotypic fusion and protein sorting (HOPS) complex mediates membrane tethering and assembles the SNARE complex to fulfill fusion ( Balderhaar and Ungermann, 2013; Krämer and Ungermann, 2011; Lürick et al., 2024 ).
