STRINGSTRING
OSH3 protein (Saccharomyces cerevisiae) - STRING interaction network
"OSH3" - Member of an oxysterol-binding protein family with seven members in S. cerevisiae 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

OSH3Member of an oxysterol-binding protein family with seven members in S. cerevisiae; family members have overlapping, redundant functions in sterol metabolism and collectively perform a function essential for viability (996 aa)    
Predicted Functional Partners:
SCS2
Integral ER membrane protein that regulates phospholipid metabolism via an interaction with the FFAT motif of Opi1p, also involved in telomeric silencing, disruption causes inositol auxotrophy above 34 degrees C, VAP homolog; Targets proteins containing a FFAT motif to endoplasmic reticulum membranes. Regulates phospholipid biosynthesis by modulating the subcellular localization of the transcriptional repressor OPI1 (244 aa)

KES1
Member of the oxysterol binding protein family, which includes seven yeast homologs; involved in negative regulation of Sec14p-dependent Golgi complex secretory functions, peripheral membrane protein that localizes to the Golgi complex; Lipid transporter involved in lipid countertransport between the Golgi complex and membranes of the endoplasmic reticulum- specifically exchanges sterol with phosphatidylinositol 4-phosphate (PI4P), delivering sterol to the Golgi in exchange for PI4P, which is degraded by the SAC1 phosphatase in the endoplasmic reticulum (PubMed-16136145, PubMed-2216213 [...] (434 aa)

SWA2
Auxilin-like protein involved in vesicular transport; clathrin-binding protein required for uncoating of clathrin-coated vesicles; Cofactor for the uncoating of clathrin-coated vesicles (CCVs) by Hsp70-type chaperones (SSA1/2/3 and SSB1/2). Coat disassembly is important for fusion of vesicles with target membranes and for recycling components of clathrin coats to the cytoplasm for further rounds of vesicle formation. Binds to assembled clathrin and recruits the ATP-activated chaperone to CCVs. Stimulates the ATPase activity of the clathrin-associated Hsp70-type chaperone SSA1, which th [...] (668 aa)

SCS22
Protein involved in regulation of phospholipid metabolism; homolog of Scs2p; similar to D. melanogaster inturned protein; Targets proteins containing a FFAT motif to membranes (By similarity). Involved in regulation of phospholipid metabolism (175 aa)
       
 
  0.816
ARP2
Essential component of the Arp2/3 complex, which is a highly conserved actin nucleation center required for the motility and integrity of actin patches; involved in endocytosis and membrane growth and polarity; Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks. Seems to contact the pointed end of the daughter actin filament (By similarity) (391 aa)
       
      0.800
SAC1
Phosphatidylinositol phosphate (PtdInsP) phosphatase involved in hydrolysis of PtdIns[4]P; transmembrane protein localizes to ER and Golgi; involved in protein trafficking and processing, secretion, and cell wall maintenance; Phosphoinositide phosphatase that hydrolyzes PtdIns(3)P and PtdIns(4)P. Has low activity towards PtdIns(3,5)P2. May be involved in the coordination of the activities of the secretory pathway and the actin cytoskeleton (623 aa)

OSH2
Member of an oxysterol-binding protein family with seven members in S. cerevisiae; family members have overlapping, redundant functions in sterol metabolism and collectively perform a function essential for viability; Lipid-binding protein involved in maintenance of intracellular sterol distribution and homeostasis. Binds to phosphoinositides (1283 aa)

ROK1
ATP-dependent RNA helicase of the DEAD box family; required for 18S rRNA synthesis; ATP-dependent RNA helicase involved in 40S ribosomal subunit biogenesis. Required for the processing and cleavage of 35S pre-rRNA at sites A0, A1, and A2, leading to mature 18S rRNA. May also have a gene-specific regulatory function since it affects nuclear fusion by regulating KAR4 expression and contributes with KEM1 to ISP-1 sensitivity (564 aa)

SKP1
Evolutionarily conserved kinetochore protein that is part of multiple protein complexes, including the SCF ubiquitin ligase complex, the CBF3 complex that binds centromeric DNA, and the RAVE complex that regulates assembly of the V-ATPase; Essential component of the E3 ubiquitin ligase complex SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins like phosphorylated SIC1. Participates in the attachment of chromosomes to the spindle. Acts as a regulatory component of the centromere DNA-binding [...] (194 aa)

CDC53
Cullin, structural protein of SCF complexes (which also contain Skp1p, Cdc34p, Hrt1p and an F-box protein) involved in ubiquitination; SCF promotes the G1-S transition by targeting G1 cyclins and the Cln-CDK inhibitor Sic1p for degradation; Core component of multiple cullin-RING-based SCF (SKP1- CUL1-F-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins.
