Golgi CORVET complex core vacuolar protein 8; Vps8 is one of the Golgi complex components necessary for vacuolar sorting. Eukaryotic cells contain a highly dynamic endo-membrane system, in which individual organelles keep their identity despite continuous vesicle generation and fusion. Vesicles that bud from a donor membrane are targeted and delivered to each individual organelle, where they release their cargo after fusion with the acceptor membrane. Vps8 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. Late endosomes form intralumenal vesicles, and the resulting multivesicular bodies fuse with the vacuole to release their cargoes. : Pssm-ID: 463718 Cd Length: 194 Bit Score: 215.11 E-value: 7.22e-64

RING finger, H2 subclass, found in vacuolar protein sorting-associated proteins Vps8, Vps11, Vps18, Vps41, and similar proteins; This subfamily corresponds to a group of vacuolar protein sorting-associated proteins containing a C-terminal C3H2C3-type RING-H2 finger, which includes Vps8, Vps11, Vps18, and Vps41. Vps11 and Vps18 associate with Vps16 and Vps33 to form a Class C Vps core complex that is required for soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNARE)-mediated membrane fusion at the lysosome-like yeast vacuole. The core complex, together with two additional compartment-specific subunits, forms the tethering complexes HOPS (homotypic vacuole fusion and protein sorting) and CORVET (class C core vacuole/endosome transport). CORVET contains the additional Vps3 and Vps8 subunits. It operates at endosomes, controls traffic into late endosomes and interacts with the Rab5/Vps21-GTP form. HOPS contains the additional Vps39 and Vps41 subunits. It operates at the lysosomal vacuole, controls all traffic from late endosomes into the vacuole and interacts with the Rab7/Ypt7-GTP form. : Pssm-ID: 438147 Cd Length: 48 Bit Score: 59.82 E-value: 1.98e-11

RING finger, H2 subclass, found in vacuolar protein sorting-associated protein 11 homolog (Vps11) and similar proteins; Vps11, also known as RING finger protein 108 (RNF108), is a soluble protein involved in regulation of glycolipid degradation and retrograde toxin transport. It is highly expressed in heart and pancreas. Vps11 associates with Vps16, Vps18, and Vps33 to form a Class C Vps core complex that is required for soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNARE)-mediated membrane fusion at the lysosome-like yeast vacuole. The core complex, together with two additional compartment-specific subunits, forms the tethering complexes HOPS (homotypic vacuole fusion and protein sorting) and CORVET (class C core vacuole/endosome transport). CORVET contains the additional Vps3 and Vps8 subunits. It operates at endosomes, controls traffic into late endosomes and interacts with the Rab5/Vps21-GTP form. HOPS contains the additional Vps39 and Vps41 subunits. It operates at the lysosomal vacuole, controls all traffic from late endosomes into the vacuole and interacts with the Rab7/Ypt7-GTP form. Vps11 is a central scaffold protein upon which both HOPS and CORVET assemble. The HOPS and CORVET complexes disassemble in the absence of Vps11, resulting in massive fragmentation of vacuoles. Vps11 contains a clathrin repeat domain and a C-terminal C3H2C3-type RING-H2 finger. This subfamily also includes Vps11 homologs found in fungi, such as Saccharomyces cerevisiae vacuolar membrane protein Pep5p, also known as carboxypeptidase Y-deficient protein 5, vacuolar morphogenesis protein 1, or vacuolar biogenesis protein END1. Pep5p is essential for vacuolar biogenesis. It associates with Pep3p to form a core Pep3p/Pep5p complex that promotes vesicular docking/fusion reactions in conjunction with SNARE proteins at multiple steps in transport routes to the vacuole.

RING finger, H2 subclass, found in vacuolar protein sorting-associated protein 41 (Vps41) and similar proteins; Vps41, also known as S53, is a protein involved in trafficking of proteins from the late Golgi to the vacuole. It interacts with caspase-8, suggesting a potential role of Vps41 beyond lysosomal trafficking. It has been identified as a potential therapeutic target for human Parkinson's disease (PD). Vps41 and the soluble N-ethylmaleimide-sensitive factor attachment protein receptors protein VAMP7 are specifically involved in the fusion of the trans-Golgi network-derived lysosome-associated membrane protein carriers with late endosomes. Vps41 is a specific subunit of the lysosomal tethering complex HOPS (homotypic vacuole fusion and protein sorting) that also includes Vps39 and a Class C Vps core complex composed of Vps11, Vps16, Vps18, and Vps33. HOPS operates at the lysosomal vacuole, controls all traffic from late endosomes into the vacuole and interacts with the Rab7/Ypt7-GTP form. The HOPS-specific Vps39 and Vps41 subunits belong to the class B Vps. They form a subcomplex that interacts with Rab7/Ypt7 and is are required for homotypic and heterotypic late endosome fusion. Vps41 contains an N-terminal WD40 repeat, one or two clathrin repeats and a C3H2C3-type RING-H2 finger domain close to its C-terminus. Pssm-ID: 438351 Cd Length: 51 Bit Score: 38.49 E-value: 7.28e-04

H2 subclass of RING (RING-H2) fingers and its variants; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). This family corresponds to the H2 subclass of RING (RING-H2) finger proteins that are characterized by containing C3H2C3-type canonical RING-H2 fingers or noncanonical RING-H2 finger variants, including C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type modified RING-H2 fingers. The canonical RING-H2 finger has been defined as C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-H-X2-C-X(4-48)-C-X2-C, X is any amino acid and the number of X residues varies in different fingers. It binds two Zn ions in a unique "cross-brace" arrangement, which distinguishes it from tandem zinc fingers and other similar motifs. RING-H2 finger can be found in a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serves as a scaffold for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enables efficient transfer of ubiquitin from E2 to the substrates.
