FAMILY

DNA mismatch repair MUTS family

CATEGORY

DNA associated

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus,chromatin/chromosome
text	MSH5 shuttles between the nucleus and the cytoplasm, being much less stable in the nucleus than in the cytoplasm

basic FUNCTION	putatively required for chromosome pairing in meiosis and DNA replicative mismatch repair
	gonadal maintenance in females
	involved in Mt DNA metabolism
	facilitating crossovers between homologs during meiosis
	playing functional roles in an array of cellular processes such as DNA damage response and meiotic homologous recombination
	involved in DNA mismatch repair (MMR) and meiotic recombination, and deficiency of MMR has been documented to have a role in lung cancer (Wang 2008)
	MutS-homologous protein required for meiotic DNA recombination
	MSH5 implicated in homologous recombination (HR)-mediated DSB repair and the DNA damage response
	MSH5 promotes HR-based DSB repair, and this property resides in the carboxyl-terminal portion of the protein

CELLULAR PROCESS	cell cycle,division,meiosis
	nucleotide, recombination
	nucleotide, repair, mismatch repair

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

heterooligomer of MSH4 and MSH5

INTERACTION

DNA

RNA

small molecule	nucleotide,
	ATP

protein	binding to MSH4
	role for MSH5 in DNA damage response involving ABL1 and TP73, suggesting that mutations impairing this process could significantly affect normal cellular responses to anti-cancer treatments
	MSH5 stimulates mtDNA repair in response to DNA damage induced by oxidative stress
	functional interplay between MSH5 and BRIP1 in double-strand break repair induced by replication stress
	MSH5 is the target of HCP5 during DNA double-strand breaks (DSBs) repair
	HCP5 regulated MSH5 expression and Granulosa cells function through direct binding with YBX1 and modulating its subcellular localization
