title: Structure and expression of the Zea mays mutS-homologs Mus1 and Mus2.
abstract: DNA mismatch repair proteins play an important role in maintaining the integrity of the genetic information during replication and homologous recombination. The MutS-homologous (MSH) and MutL-homologous (MLH) proteins are highly conserved among all prokaryotes and eukaryotes. We have isolated two mutS homologous genes from Zea mays, named Mus1 and Mus2. Phylogenetic analysis identifies Mus1 as a member of the MSH2 protein family. Mus2 is an ortholog of the Arabidopsis thaliana MSH7 protein and belongs to a subgroup of MSH proteins that is possibly plant-specific. Mus1 and Mus2 are expressed at very low levels. Mus1 is located on chromosome 7L near locus b32B, and mus2 maps on chromosome 3S.
