This entry represents the RING C-terminal domain in VPS18 proteins. VPS18 proteins are involved in vesicle-mediated protein trafficking to lysosomal compartments, playing a crucial role in endocytic membrane transport and autophagic pathways. They act as a core component of the HOPS and CORVET endosomal tethering complexes, facilitating the conversion of Rab5 to Rab7 endosomes and mediating tethering and docking events during SNARE-mediated membrane fusion. The HOPS complex is recruited to Rab7 on the late endosomal membrane, regulating late endocytic, phagocytic, and autophagic traffic towards lysosomes. The CORVET complex functions as a Rab5 effector, mediating early endosome fusion. These proteins are essential for processes such as vacuolar biogenesis, lysosome biogenesis, and the degradation of apoptotic cells. They also play roles in embryogenesis, root development, and dendrite development in various organisms [5-6]. This domain is a specialised type of Zn-finger of 40 to 60 residues that binds two atoms of zinc, and is probably involved in mediating protein-protein interactions [11].

Vps8 is one of the Golgi complex components necessary for vacuolar sorting. It is the core component of the endosomal tethering complex CORVET (class C core vacuole/endosome tethering). Vps8 co-operates with Vps21-GTP to mediate endosomal clustering in a reaction that is dependent on Vps3. Vps8 is the only CORVET subunit that is enriched on late endosomes, suggesting that it is a marker for the maturation of late endosomes [1,2]. These proteins consist of a beta-propeller at the N-terminal followed by a long, central TPR domain and a RING zinc finger at the C-terminal. This entry represents the RING zinc finger found in yeast Vps8 and similar sequences.
