STRINGSTRING
RFU1 protein (Saccharomyces cerevisiae) - STRING interaction network
"RFU1" - Protein that inhibits Doa4p deubiquitinating activity 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

RFU1Protein that inhibits Doa4p deubiquitinating activity; contributes to ubiquitin homeostasis by regulating the conversion of free ubiquitin chains to ubiquitin monomers by Doa4p; GFP-fusion protein localizes to endosomes; Inhibitor of the DOA4 deubiquitinase involved in the regulation of protein degradation by the proteasome and maintenance of a normal level of free ubiquitin (200 aa)    
Predicted Functional Partners:
DOA4
Ubiquitin isopeptidase, required for recycling ubiquitin from proteasome-bound ubiquitinated intermediates, acts at the late endosome/prevacuolar compartment to recover ubiquitin from ubiquitinated membrane proteins en route to the vacuole; Ubiquitin thioesterase that acts at the late endosome/prevacuolar compartment to recover ubiquitin from ubiquitinated membrane proteins en route to the vacuole. Removes also ubiquitin from soluble proteins targeted to proteasomes. Is essential to maintain a normal level of free ubiquitin. Involved in the ammonium-induced down-regulation of the GAP1 [...] (926 aa)

BRO1
Cytoplasmic class E vacuolar protein sorting (VPS) factor; coordinates deubiquitination in the multivesicular body (MVB) pathway by recruiting Doa4p to endosomes; Class E VPS protein involved in concentration and sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles. Fusion between endosomes and the vacuole will then target the cargo proteins to the vacuolar lumen. Acts as an adapter that recruits the DOA4 deubiquitinase to the endosomes, leading to deubiquitination of cargo proteins prior to the lumenal sequestration. Its association t [...] (844 aa)

UBP14
Ubiquitin-specific protease; specifically disassembles unanchored ubiquitin chains; involved in fructose-1,6-bisphosphatase (Fbp1p) degradation; similar to human isopeptidase T; Has a role in the negative regulation of gluconeogenesis. Required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBPase). Accelerates proteasomal breakdown of ubiquitinated proteins as it disassembles free ubiquitin chains that would compete with ubiquitinated proteins to bind to the proteasome (781 aa)

RPT1
One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; required for optimal CDC20 transcription; interacts with Rpn12p and Ubr1p; mutant has aneuploidy tolerance; The 26S protease is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex (By similarity) (467 aa)
       
 
  0.679
CDC48
AAA ATPase; subunit of polyubiquitin-selective segregase complex involved in ERAD, cell wall integrity during heat stress, mitotic spindle disassembly; role in mobilizing membrane bound transcription factors by regulated ubiquitin/proteasome-dependent processing in macroautophagy, PMN, RAD, ribophagy, homotypic ER membrane fusion, disassembly of Met30p from SCF complex, telomerase regulation via Est1p degradation; human ortholog VCP can complement yeast cdc48 mutant; Involved in spindle disassembly, degradation of ubiquitinated proteins and protein export from the endoplasmic reticulum [...] (835 aa)
       
 
  0.658
RPN2
Subunit of the 26S proteasome, substrate of the N-acetyltransferase Nat1p; Acts as a regulatory subunit of the 26S proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins (945 aa)
       
      0.647
NOG2
Putative GTPase that associates with pre-60S ribosomal subunits in the nucleolus and is required for their nuclear export and maturation; GTPase that associates with pre-60S ribosomal subunits in the nucleolus and is required for their nuclear export and maturation (486 aa)
     
        0.637
YNL203C
Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data (203 aa)
           
  0.575
VTS1
Post-transcriptional gene regulator, flap-structured DNA-binding and RNA-binding protein; shows genetic interactions with Vti1p, a v-SNARE involved in cis-Golgi membrane traffic; stimulates Dna2p endonuclease activity; contains a SAM domain; RNA-binding protein involved in post-transcriptional regulation through transcript degradation of SRE (SMG-recognition elements) bearing mRNAs. May be involved in vacuolar protein transport (523 aa)
     
        0.553
AAH1
Adenine deaminase (adenine aminohydrolase), converts adenine to hypoxanthine; involved in purine salvage; transcriptionally regulated by nutrient levels and growth phase; Aah1p degraded upon entry into quiescence via SCF and the proteasome; Catalyzes the hydrolytic deamination of adenine to hypoxanthine. Plays an important role in the purine salvage pathway and in nitrogen catabolism. Also exhibits a low activity towards N(6)-substituted adenines that are commonly known as the plant hormones cytokinins (347 aa)
