STRINGSTRING
USB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"USB1" - Essential protein that localizes to the nucleus and mitochondria 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

USB1Essential protein that localizes to the nucleus and mitochondria; overexpression suppresses the respiratory defects of oxa1 and mtf2 mutants; Phosphodiesterase responsible for the U6 snRNA 3’ end processing. Acts as an exoribonuclease (RNase) responsible for trimming the poly(U) tract of the last nucleotides in the pre-U6 snRNA molecule, leading to the formation of mature U6 snRNA 3’ end-terminated with a 3’phosphate. Could be involved in aerobic respiration (290 aa)    
Predicted Functional Partners:
QCR2
Subunit 2 of the ubiquinol cytochrome-c reductase complex, which is a component of the mitochondrial inner membrane electron transport chain; phosphorylated; transcription is regulated by Hap1p, Hap2p/Hap3p, and heme; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c. QCR2 is required for the assembly of the complex (368 aa)
       
      0.844
COR1
Core subunit of the ubiquinol-cytochrome c reductase complex (bc1 complex), which is a component of the mitochondrial inner membrane electron transport chain; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c. COR1 may mediate formation of the complex between cytochromes c and c1 (457 aa)
       
      0.719
YJL193W
Putative protein of unknown function, predicted to encode a triose phosphate transporter subfamily member based on phylogenetic analysis; similar to YOR307C/SLY41; deletion mutant has a respiratory growth defect (402 aa)
           
  0.697
YDR186C
Protein of unknown function; may interact with ribosomes, based on co-purification experiments; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm (877 aa)
           
  0.697
PRP19
Splicing factor associated with the spliceosome; contains a U-box, a motif found in a class of ubiquitin ligases, and a WD40 domain; Probable ubiquitin-protein ligase involved in pre-mRNA splicing. Acts as a central component of the NTC complex (or PRP19-associated complex) that associates to the spliceosome to mediate conformational rearrangement or to stabilize the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation. It is also probably involved in DNA repair (503 aa)
       
      0.692
CWC22
Spliceosome-associated protein that is required for pre-mRNA splicing; necessary for Prp2p function at the first catalytic step of splicing; has similarity to S. pombe Cwf22p; CWC22 is an essential protein; May be involved in pre-mRNA splicing (577 aa)
       
      0.688
YGL034C
Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data (121 aa)
           
  0.679
UBS1
Ubiquitin-conjugating enzyme suppressor that functions as a general positive regulator of Cdc34p activity; nuclear protein that may represent a link between nucleocytoplasmic transport and ubiquitin ligase activity; Not known; its elevated expression suppresses the conditional cell cycle defects associated with UBC3/CDC34 mutations (277 aa)
           
  0.637
SLY41
Protein involved in ER-to-Golgi transport; Able to suppress the functional loss of YPT1. May form a channel. Protein SLY41 is not essential for cell viability. The SLY41 gene is a multicopy suppressor (453 aa)
           
  0.580
OSW7
Putative protein of unknown function; may be involved in response to high salt and changes in carbon source; deletion mutant has decreased spore survival in Drosophila feces; Involved in spore wall assembly (510 aa)
           
  0.578
