At4g02070: MSH6 (MUTS HOMOLOG 6)

encodes a DNA mismatch repair homolog of human MutS gene, MSH6. There are four MutS genes in Arabidopsis, MSH2, MSH3, MSH6, and MSH7, which all act as heterodimers and bind to 51-mer duplexes. MSH2*MSH6 bound the ( T) substrate strongly, (T/G) well, and ( AAG) no better than it did a (T/A) homoduplex.
