STRINGSTRING
CPR7 protein (Saccharomyces cerevisiae) - STRING interaction network
"CPR7" - Peptidyl-prolyl cis-trans isomerase 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

CPR7Peptidyl-prolyl cis-trans isomerase (cyclophilin), catalyzes the cis-trans isomerization of peptide bonds N-terminal to proline residues; binds to Hsp82p and contributes to chaperone activity; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Plays a major role in negative regulation of the heat shock transcription factor (HSF) (393 aa)    
Predicted Functional Partners:
STI1
Hsp90 cochaperone, interacts with the Ssa group of the cytosolic Hsp70 chaperones and activates Ssa1p ATPase activity; interacts with Hsp90 chaperones and inhibits their ATPase activity; homolog of mammalian Hop; May play a role in mediating the heat shock response of some HSP70 genes. It is required for optimal growth of yeast cells at both low and high temperature (589 aa)
     
 
  0.970
CNS1
TPR-containing co-chaperone; binds both Hsp82p (Hsp90) and Ssa1p (Hsp70) and stimulates the ATPase activity of SSA1, ts mutants reduce Hsp82p function while over expression suppresses the phenotypes of an HSP82 ts allele and a cpr7 deletion; Co-chaperone that binds to the molecular chaperones Hsp90 (HSC82 and HSP82) and Hsp70 (SSA1). Stimulates SSA1 ATPase activity, but not Hsp90 ATPase activity. Involved in only a subset of Hsp90 functions (385 aa)
   
 
  0.967
HSP82
Hsp90 chaperone required for pheromone signaling and negative regulation of Hsf1p; docks with Tom70p for mitochondrial preprotein delivery; promotes telomerase DNA binding and nucleotide addition; interacts with Cns1p, Cpr6p, Cpr7p, Sti1p; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. The nucleotide-free form of the dimer is found in an open conformation in which the N-termini are not dim [...] (709 aa)
   
 
  0.955
HSC82
Cytoplasmic chaperone of the Hsp90 family, redundant in function and nearly identical with Hsp82p, and together they are essential; expressed constitutively at 10-fold higher basal levels than HSP82 and induced 2-3 fold by heat shock; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction such as CNA2. Undergoes a functional cycle that is linked to its ATPase activity (By similarity). Interacts dynamically with various co-chaperones that modulate its substrate reco [...] (705 aa)
   
 
  0.942
SBA1
Co-chaperone that binds to and regulates Hsp90 family chaperones; important for pp60v-src activity in yeast; homologous to the mammalian p23 proteins and like p23 can regulate telomerase activity; Acts as a co-chaperone (216 aa)
     
 
  0.892
HSP104
Heat shock protein that cooperates with Ydj1p (Hsp40) and Ssa1p (Hsp70) to refold and reactivate previously denatured, aggregated proteins; responsive to stresses including- heat, ethanol, and sodium arsenite; involved in [PSI+] propagation; Required, in concert with Hsp40 (YDJ1) and Hsp70 (SSA1) and small Hsps (HSP26), for the dissociation, resolubilization and refolding of aggregates of damaged proteins after heat or other environmental stresses. Extracts proteins from aggregates by unfolding and threading them in an ATP-dependent process through the axial channel of the protein hexa [...] (908 aa)
   
 
  0.888
PRP4
Splicing factor, component of the U4/U6-U5 snRNP complex; Involved in RNA splicing. Is required for the association of U4/U6 snRNP with U5 snRNP in an early step of spliceosome assembly (465 aa)
     
 
  0.856
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)

TOP2
Topoisomerase II, relieves torsional strain in DNA by cleaving and re-sealing the phosphodiester backbone of both positively and negatively supercoiled DNA; cleaves complementary strands; localizes to axial cores in meiosis; Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes (1428 aa)
   
 
  0.845
BUD31
Component of the SF3b subcomplex of the U2 snRNP; diploid mutants display a random budding pattern instead of the wild-type bipolar pattern; Involved in pre-mRNA splicing. Important for bud site selection (157 aa)
