  • Function
    Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS beta which binds to DNA mismatches thereby initiating DNA repair. When bound, the MutS beta heterodimer bends the DNA helix and shields approximately 20 base pairs. MutS beta recognizes large insertion-deletion loops (IDL) up to 13 nucleotides long. After mismatch binding, forms a ternary complex with the MutL alpha heterodimer, which is thought to be responsible for directing the downstream MMR events, including strand discrimination, excision, and resynthesis.
  • Involvement in disease
    Defects in MSH3 are a cause of susceptibility to endometrial cancer (ENDMC) [MIM:608089].
  • Sequence similarities
    Belongs to the DNA mismatch repair mutS family. MSH3 subfamily.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.

Anti-MSH3 antibody images

  • ab93663, at a 1/100 dilution, staining MSH3 in formalin fixed, paraffin embedded Human rectal carcinoma tissue by Immunohistochemistry.
  • ICC/IF image of ab93663 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab93663, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h.Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
