In eukaryotes from yeast to humans, MSH2 dimerizes with MSH6 to form the MutSα complex, which is involved in base mismatch repair and short insertion/deletion loops.
En eucariotas desde os lévedos aos humanos, a MSH2 dimerízase con MSH6 para formar o complexo MutSα, que intervén na reparación de discordancias de bases e curtos bucles de inserción/deleción.
