STRINGSTRING
PMS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PMS1" - ATP-binding protein required for mismatch repair in mitosis and meiosis 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

PMS1ATP-binding protein required for mismatch repair in mitosis and meiosis; functions as a heterodimer with Mlh1p, binds double- and single-stranded DNA via its N-terminal domain, similar to E. coli MutL; Required for DNA mismatch repair (MMR), correcting base- base mismatches and insertion-deletion loops (IDLs) resulting from DNA replication, DNA damage or from recombination events between non-identical sequences during meiosis. Component of the MutLalpha heterodimer that forms a ternary complex with the MutS heterodimers, which initially recognize the DNA mismatches. This complex is tho [...] (873 aa)    
Predicted Functional Partners:
MSH2
Protein that forms heterodimers with Msh3p and Msh6p that bind to DNA mismatches to initiate the mismatch repair process; contains a Walker ATP-binding motif required for repair activity; Msh2p-Msh6p binds to and hydrolyzes ATP; Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers- MutS alpha (MSH2- MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer), which bind to DNA mismatches thereby initiating DNA repair. MSH2 seems to act as a scaffold for the other MutS homologs that provide substrate-binding and substrate specificity. When bou [...] (964 aa)

MSH6
Protein required for mismatch repair in mitosis and meiosis, forms a complex with Msh2p to repair both single-base & insertion-deletion mispairs; potentially phosphorylated by Cdc28p; Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS alpha, which binds to DNA mismatches thereby initiating DNA repair. MSH6 provides substrate-binding and substrate specificity to the complex. When bound, MutS alpha bends the DNA helix and shields approximately 20 base pairs. Acts mainly to repair base-base and single insertion-deletion mismatches th [...] (1242 aa)

MSH3
Mismatch repair protein, forms dimers with Msh2p that mediate repair of insertion or deletion mutations and removal of nonhomologous DNA ends, contains a PCNA (Pol30p) binding motif required for genome stability; Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS beta, which binds to DNA mismatches thereby initiating DNA repair. MSH3 provides substrate-binding and substrate specificity to the complex. When bound, the MutS beta heterodimer bends the DNA helix and shields approximately 20 base pairs. Acts mainly to repair insertion- [...] (1018 aa)

MLH1
Protein required for mismatch repair in mitosis and meiosis as well as crossing over during meiosis; forms a complex with Pms1p and Msh2p-Msh3p during mismatch repair; human homolog is associated with hereditary non-polyposis colon cancer; Required for DNA mismatch repair (MMR), correcting base- base mismatches and insertion-deletion loops (IDLs) resulting from DNA replication, DNA damage or from recombination events between non-identical sequences during meiosis. Component of different MutL heterodimers that form a ternary complex with the MutS heterodimers, which initially recognize [...] (769 aa)

EXO1
5’-3’ exonuclease and flap-endonuclease involved in recombination, double-strand break repair and DNA mismatch repair; member of the Rad2p nuclease family, with conserved N and I nuclease domains; 5’->3’ double-stranded DNA exonuclease involved in mismatch repair and eventually also in mitotic recombination between direct repeats. Also has a minor role in the correction of large DNA mismatches that occur in the heteroduplex DNA during meiotic recombination at the HIS4 locus (702 aa)
     
  0.998
POL30
Proliferating cell nuclear antigen (PCNA), functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Involved in DNA repair (258 aa)

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)

MSH1
DNA-binding protein of the mitochondria involved in repair of mitochondrial DNA, has ATPase activity and binds to DNA mismatches; has homology to E. coli MutS; transcription is induced during meiosis; Important for mitochondrial DNA (mtDNA) stability and repair. Recognizes and binds to base-base and small insertion- deletion mismatches in mtDNA. ATP binding and hydrolysis is crucial for function. Binding to a mismatched base pair attenuates ATP hydrolysis. Also involved in proper sorting of mtDNA during mtDNA transmission (959 aa)

DIN7
Mitochondrial nuclease functioning in DNA repair and replication, modulates the stability of the mitochondrial genome, induced by exposure to mutagens, also induced during meiosis at a time nearly coincident with commitment to recombination; 5’->3’ double-stranded DNA exonuclease (430 aa)
