STRINGSTRING
MSH1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MSH1" - DNA-binding protein of the mitochondria involved in repair of mitochondrial DNA, has ATPase activity and binds to DNA mismatches 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

MSH1DNA-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)
