MSH2 is a 100-106kD member of the mutS family of DNA mismatch repair molecules.
It is a DNA binding protein that is expressed in rapidly proliferating cells, and acts in concert with multiple subunits.
MSH2 forms a heterodimer with MSH6, forming MutS.
This dimer recognizes and repairs both nucleotide misparings and one or two aberrant nucleotide insertions/deletions.
MSH2 also heterodimerizes with MSH3, forming MutSB.
This complex acts on DNA double-stranded breaks, and repairs large nucleotide insertions/deletions (<15 bases).
MutSA is associated with BLM:p53:RAD51 complexes, while MSH2B is associated with SLX4/BTBD12 complexes.
Human MSH2 is 934aa in length.
It contains three MutS domains aa18-132; 158-284; 297-612 plus an ABC transporter signature motif that may hydrolyze ATP aa 633-852.
There are multiple splice variants.
One shows a premature truncation after His429, while others contain a 46aa substitution for aa879-934, a 29aa substitution for aa462-934, a 28aa substitution for aa783-934, a 3aa substitution for aa532-934, a 5aa substitution for aa482-934 and a 31aa substitution for aa379-934.
Over aa1-140, human MSH2 shares 94% aa identity with mouse MSH2.
