STRINGSTRING
FES1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FES1" - Hsp70 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

FES1Hsp70 (Ssa1p) nucleotide exchange factor, cytosolic homolog of Sil1p, which is the nucleotide exchange factor for BiP (Kar2p) in the endoplasmic reticulum; Involved in protein translation, propagation of [PSI+] prions, and polyamine tolerance. Functions as a nucleotide exchange factor (NEF), which accelerates the release of ADP, for the cytosolic Hsp70 chaperone SSA1 and the ribosome-associated Hsp70 chaperone SSB1. Required for fully efficient Hsp70-mediated folding of proteins (290 aa)    
Predicted Functional Partners:
BTN2
v-SNARE binding protein that facilitates specific protein retrieval from a late endosome to the Golgi; modulates arginine uptake, possible role in mediating pH homeostasis between the vacuole and plasma membrane H(+)-ATPase; V-SNARE binding protein that facilitates specific protein retrieval from a late endosome to the Golgi. Modulates the rate of arginine uptake. Involved in pH homeostasis. Required for the correct localization of IST2. May be involved in ion homeostasis together with IST2 (410 aa)

SIS1
Type II HSP40 co-chaperone that interacts with the HSP70 protein Ssa1p; not functionally redundant with Ydj1p due to due to substrate specificity; shares similarity with bacterial DnaJ proteins; Required for nuclear migration during mitosis. It is required for the normal initiation of translation. Might mediate the dissociation of a specific protein complex of the translation machinery. Essential for viability (352 aa)
     
 
  0.978
SSA1
ATPase involved in protein folding and nuclear localization signal (NLS)-directed nuclear transport; member of heat shock protein 70 (HSP70) family; forms a chaperone complex with Ydj1p; localized to the nucleus, cytoplasm, and cell wall; 98% identi /.../th Ssa2p, but subtle differences between the two proteins provide functional specificity with respect to propagation of yeast [URE3] prions and vacuolar-mediated degradations of gluconeogenesis enzymes; May play a role in the transport of polypeptides both across the mitochondrial membranes and into the endoplasmic reticulum. A functio [...] (642 aa)
       
 
  0.929
HSP42
Small heat shock protein (sHSP) with chaperone activity; forms barrel-shaped oligomers that suppress unfolded protein aggregation; involved in cytoskeleton reorganization after heat shock (375 aa)
     
 
  0.916
SSE1
ATPase that is a component of the heat shock protein Hsp90 chaperone complex; binds unfolded proteins; member of the heat shock protein 70 (HSP70) family; localized to the cytoplasm; Has a calcium-dependent calmodulin-binding activity. Required for normal growth at various temperatures (693 aa)
     
 
  0.895
OPI10
Protein with a possible role in phospholipid biosynthesis, based on inositol-excreting phenotype of the null mutant and its suppression by exogenous choline; Involved in phospholipid biosynthesis (246 aa)
     
        0.835
SSA4
Heat shock protein that is highly induced upon stress; plays a role in SRP-dependent cotranslational protein-membrane targeting and translocation; member of the HSP70 family; cytoplasmic protein that concentrates in nuclei upon starvation (642 aa)
     
 
  0.817
TIF1
Translation initiation factor eIF4A, identical to Tif2p; DEA(D/H)-box RNA helicase that couples ATPase activity to RNA binding and unwinding; forms a dumbbell structure of two compact domains connected by a linker; interacts with eIF4G; ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5’-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning fo [...] (395 aa)

SNL1
Protein of unknown function proposed to be involved in nuclear pore complex biogenesis and maintenance as well as protein folding; has similarity to the mammalian BAG-1 protein; Stimulator of ATPase activity of molecular chaperones of the HSP70 family (principally of the SSA class). Stimulation is important for HSP70-substrate complex dissociation after folding of newly synthesized or refolded proteins. SNL1 is probably involved in nuclear pore biogenesis and in particular the folding or refolding of misfolded NUP116, GLE2 and NIC96 (159 aa)

SSE2
Member of the heat shock protein 70 (HSP70) family; may be involved in protein folding; localized to the cytoplasm; highly homologous to the heat shock protein Sse1p; Has a calcium-dependent calmodulin-binding activity (693 aa)
