STRINGSTRING
PCH2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PCH2" - Nucleolar component of the pachytene checkpoint, which prevents chromosome segregation when recombination and chromosome synapsis are defective 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

PCH2Nucleolar component of the pachytene checkpoint, which prevents chromosome segregation when recombination and chromosome synapsis are defective; also represses meiotic interhomolog recombination in the rDNA; Required for the pachytene checkpoint, the meiotic checkpoint that prevents chromosome segregation when defects in recombination and synaptonemal complex formation occurred. Represses meiotic recombination in the rDNA, probably by excluding the meiosis-specific protein HOP1 from the nucleolar region (564 aa)    
Predicted Functional Partners:
DMC1
Meiosis-specific protein required for repair of double-strand breaks and pairing between homologous chromosomes; homolog of Rad51p and the bacterial RecA protein; Required for meiotic recombination, synaptonemal complex formation and cell cycle progression. Recruited to meiosis recombination hotspots by MEI5 and SAE3 (334 aa)
   
 
  0.950
ZIP1
Transverse filament protein of the synaptonemal complex; required for normal levels of meiotic recombination and pairing between homologous chromosome during meiosis; potential Cdc28p substrate; Required for meiotic chromosome synapsis and cell cycle progression. May act as a molecular zipper to bring homologous chromosomes in close apposition. ZIP1 may encode the transverse filaments of the synaptonemal complex (875 aa)
       
 
  0.932
SPO11
Meiosis-specific protein that initiates meiotic recombination by catalyzing the formation of double-strand breaks in DNA via a transesterification reaction; required for homologous chromosome pairing and synaptonemal complex formation; Required for meiotic recombination. Mediates DNA cleavage that forms the double-strand breaks (DSB) that initiate meiotic recombination. The action of SPO11 is important in setting off a regulatory chain of events encompassing 5’ to 3’ resection. When there are no SPO11-DSBs, resection of a site specific VDE-DSB takes place but it is faster than in wild- [...] (398 aa)
     
 
  0.928
ZIP2
Meiosis-specific protein involved in normal synaptonemal complex formation and pairing between homologous chromosomes during meiosis; Required for initiation of meiotic chromosome synapsis. Involved in synaptonemal complex formation, a structure that tethers a pair of homologous chromosomes along their lengths and plays a central role in recombination and homolog segregation during meiosis. Required for the normal localization of MSH4 to chromosomes (704 aa)
       
 
  0.924
RAD17
Checkpoint protein, involved in the activation of the DNA damage and meiotic pachytene checkpoints; with Mec3p and Ddc1p, forms a clamp that is loaded onto partial duplex DNA; homolog of human and S. pombe Rad1 and U. maydis Rec1 proteins; Component of the checkpoint clamp complex involved in the surveillance mechanism that allows the DNA repair pathways to act to restore the integrity of the DNA prior to DNA synthesis or separation of the replicated chromosomes. Associates with sites of DNA damage and modulates the MEC1 signaling pathway and the activation of RAD53 in response to DNA [...] (401 aa)
       
 
  0.872
MSH4
Protein involved in meiotic recombination, required for normal levels of crossing over, colocalizes with Zip2p to discrete foci on meiotic chromosomes, has homology to bacterial MutS protein; Involved in meiotic recombination. Facilitate crossovers between homologs during meiosis (878 aa)
   
 
  0.852
NDT80
Meiosis-specific transcription factor required for exit from pachytene and for full meiotic recombination; activates middle sporulation genes; competes with Sum1p for binding to promoters containing middle sporulation elements (MSE); Transcription factor required for successful completion of meiosis and spore formation. Gets activated after completion of meiotic recombination at the end of prophase I. Recognizes and binds to the middle sporulation element (MSE) 5’-C[AG]CAAA[AT]-3’ in the promoter region of stage-specific genes that are required for progression through meiosis and sporu [...] (627 aa)
       
 
  0.831
MEK1
Meiosis-specific serine/threonine protein kinase, functions in meiotic checkpoint, promotes recombination between homologous chromosomes by suppressing double strand break repair between sister chromatids; Probable protein kinase required for meiotic recombination (497 aa)
     
 
  0.828
HOP1
Meiosis-specific DNA binding protein that displays Red1p dependent localization to the unsynapsed axial-lateral elements of the synaptonemal complex; required for homologous chromosome synapsis and chiasma formation; Probable constituent of the synaptonemal complex during meiosis. May interact with RED1 (605 aa)
     
 
  0.813
MSH5
Protein of the MutS family, forms a dimer with Msh4p that facilitates crossovers between homologs during meiosis; msh5-Y823H mutation confers tolerance to DNA alkylating agents; homologs present in C. elegans and humans; Involved in meiotic recombination. Facilitate crossovers between homologs during meiosis (901 aa)
