STRINGSTRING
VPS9 protein (Saccharomyces cerevisiae) - STRING interaction network
"VPS9" - A guanine nucleotide exchange factor involved in vesicle-mediated vacuolar protein transport in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

VPS9A guanine nucleotide exchange factor involved in vesicle-mediated vacuolar protein transport; specifically stimulates the intrinsic guanine nucleotide exchange activity of Vps21p/Rab5- similar to mammalian ras inhibitors; binds ubiquitin; Required for vacuolar protein sorting; may be required for the consumption of transport vesicles containing vacuolar protein precursors. May bind a Rab GTPase such as VPS21 (451 aa)    
Predicted Functional Partners:
VPS21
Rab family GTPase required for endocytic transport and for sorting of vacuolar hydrolases; localized in endocytic intermediates; detected in mitochondria; geranylgeranylation required for membrane association; mammalian Rab5 homolog; Required for protein transport to the vacuole. Involved in two vesicle trafficking steps to the prevacuolar compartment (PVC), regulating the docking of endosomes and Golgi vesicles to the PVC by interacting with PEP7/VAC1 on the PVC membrane and promoting SNARE complex formation (210 aa)

YPT53
Rab family GTPase, similar to Ypt51p and Ypt52p and to mammalian rab5; required for vacuolar protein sorting and endocytosis; Required for transport in the endocytic pathway and for correct sorting of the vacuolar hydrolases suggesting a possible intersection of the endocytic with the vacuolar sorting pathway (220 aa)

YPT52
Rab family GTPase, similar to Ypt51p and Ypt53p and to mammalian rab5; required for vacuolar protein sorting and endocytosis; Required for transport in the endocytic pathway and for correct sorting of the vacuolar hydrolases suggesting a possible intersection of the endocytic with the vacuolar sorting pathway (234 aa)

YPT10
Rab family GTP-binding protein; contains the PEST signal sequence specific for proteolytic enzymes; may be involved in vesicular transport; overexpression leads to accumulation of Golgi-like cisternae with budding vesicles; Protein transport. Probably involved in vesicular traffic (By similarity). Specifically binds guanine nucleotides (199 aa)

UBI4
Ubiquitin, becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiqui [...] (381 aa)

RPS31
Fusion protein that is cleaved to yield a ribosomal protein of the small (40S) subunit and ubiquitin; ubiquitin may facilitate assembly of the ribosomal protein into ribosomes; interacts genetically with translation factor eIF2B; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear [...] (152 aa)

MUK1
Cytoplasmic protein of unknown function containing a Vps9 domain; computational analysis of large-scale protein-protein interaction data suggests a possible role in transcriptional regulation; Putative GTPase-activating protein (612 aa)
       
 
  0.921
MON1
Protein required for fusion of cvt-vesicles and autophagosomes with the vacuole; associates, as a complex with Ccz1p, with a perivacuolar compartment; potential Cdc28p substrate; In complex with CCZ1, is required for multiple vacuole delivery pathways including the cytoplasm to vacuole transport (Cvt), autophagy, pexophagy and endocytosis. The CCZ1-MON1 complex acts at the fusion of vesicles with the vacuole, through its regulation of the SNARE complex during the coordinated priming and docking stages of fusion, and particularly at the stage of tethering/docking (644 aa)
