STRINGSTRING
SQS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SQS1" - Stimulates the ATPase and helicase activities of Prp43p 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

SQS1Stimulates the ATPase and helicase activities of Prp43p; acts with Prp43p to stimulate 18s rRNA maturation by Nob1p; overexpression antagonizes the suppression of splicing defects by spp382 mutants; component of pre-ribosomal particles; May be involved in splicing since overexpression antagonizes the suppression of splicing defects by SPP382 mutants (767 aa)    
Predicted Functional Partners:
PRP43
RNA helicase in the DEAH-box family, functions in both RNA polymerase I and polymerase II transcript metabolism, involved in release of the lariat-intron from the spliceosome; Pre-mRNA processing factor involved in disassembly of spliceosomes after the release of mature mRNA (767 aa)
       
 
  0.978
SPP382
Essential protein that forms a dimer with Ntr2p; also forms a trimer, with Ntr2p and Prp43p, that is involved in spliceosome disassembly; found also in a multisubunit complex with the splicing factor Clf1p; suppressor of prp38-1 mutation; Involved in pre-mRNA splicing and spliceosome disassembly. Promotes release of excised lariat intron from the spliceosome by acting as a receptor for PRP43. This targeting of PRP43 leads to disassembly of the spliceosome with the separation of the U2, U5, U6 snRNPs and the NTC complex (708 aa)
       
 
  0.809
CWC23
Component of a complex containing Cef1p, putatively involved in pre-mRNA splicing; has similarity to E. coli DnaJ and other DnaJ-like proteins and to S. pombe Cwf23p; Involved in pre-mRNA splicing. May be involved in endoplasmic reticulum-associated protein degradation (ERAD) and required for growth at low and high temperatures (283 aa)
       
 
  0.786
NOB1
Essential nuclear protein involved in proteasome maturation and synthesis of 40S ribosomal subunits; required for cleavage of the 20S pre-rRNA to generate the mature 18S rRNA; Required for the synthesis of 40S ribosome subunits. Has a role in processing 20S pre-rRNA into the mature 18S rRNA, where it is required for cleavage at the 3’ end of the mature 18S rRNA (D-site). Accompanies the 20S pre-rRNA from the nucleus to the cytoplasm. In association with NIN1, may promote the recruitment of the proteasome to the ribosomal subunits stalled in maturation (459 aa)
           
  0.579
PFA3
Palmitoyltransferase for Vac8p, required for vacuolar membrane fusion; contains an Asp-His-His-Cys-cysteine rich (DHHC-CRD) domain; autoacylates; required for vacuolar integrity under stress conditions; Palmitoyltransferase specific for VAC8. Palmitoylates VAC8 at one or more of its N-terminal cysteine residues, which is required for its proper membrane localization (336 aa)
           
  0.577
LTV1
Component of the GSE complex; GSE is required for proper sorting of amino acid permease Gap1p; required for ribosomal small subunit export from nucleus; required for growth at low temperature; Involved in protein transport. Non-ribosomal factor required for efficient nuclear export of the ribosomal 40S subunit. Component of the GSE complex, a GTPase complex required for intracellular sorting of GAP1 out of the endosome (463 aa)
           
  0.574
PXR1
Essential protein involved in rRNA and snoRNA maturation; competes with TLC1 RNA for binding to Est2p, suggesting a role in negative regulation of telomerase; human homolog inhibits telomerase; contains a G-patch RNA interacting domain; Involved in rRNA-processing at A0, A1 and A2 sites through its action in U18 and U24 snoRNA 3’-end final trimming. Negative regulator of telomerase through competition for binding to EST2 with TLC1 (271 aa)
           
  0.573
TSR1
Protein required for processing of 20S pre-rRNA in the cytoplasm; associates with pre-40S ribosomal particles; inhibits the premature association of 60S subunits with assembling 40S subunits in the cytoplasm; similar to Bms1p; Required for 40S ribosomal subunit synthesis. Required for normal export of the pre-40S particles from the nucleus to the cytoplasm. Its subcellular location and association with pre-40S subunitshifts from mixed cytoplasm/nucleus to all nuclear in RPS19 disruptions, suggesting it acts after the ribosomal protein (788 aa)
           
  0.570
BMS1
GTPase required for synthesis of 40S ribosomal subunits and for processing the 35S pre-rRNA at sites A0, A1, and A2; interacts with Rcl1p, which stimulates its GTPase and U3 snoRNA binding activities; has similarity to Tsr1p; May act as a molecular switch during maturation of the 40S ribosomal subunit in the nucleolus. The depletion of BMS1 interferes with processing of the 35S pre-rRNA at sites A0, A1, and A2, and the formation of 40S subunits (1183 aa)

DHR2
Predominantly nucleolar DEAH-box ATP-dependent RNA helicase, required for 18S rRNA synthesis; Probable ATP-binding RNA helicase. Required for 18S rRNA synthesis (735 aa)
