Result: Positive
Affinity and binding kinetics of CPTC-MSH3-1 and BSA-conjugated peptide, "CDLSDFPLIK", were measured using biolayer interferometry. BSA-conjugated peptide was amine coupled over AR2G bio- sensors. Rabbit antibody CPTC-MSH3-1 was used as analyte and was titrated at 1024 nM, 256 nM, 64 nM, 16 nM, and 4 nM. Buffer only and biosensors immobilized without peptide were used as references for background subtraction. All binding data were double referenced and analyzed globally using a 1:2 bivalent fitting model.

Function:
The protein encoded by this gene forms a heterodimer with MSH2 to form MutS beta, part of the post-replicative DNA mismatch repair system. MutS beta initiates mismatch repair by binding to a mismatch and then forming a complex with MutL alpha heterodimer. This gene contains a polymorphic 9 bp tandem repeat sequence in the first exon. The repeat is present 6 times in the reference genome sequence and 3-7 repeats have been reported. Defects in this gene are a cause of susceptibility to endometrial cancer.MSH3 (MutS Homolog 3) is a Protein Coding gene. Diseases associated with MSH3 include Familial Adenomatous Polyposis 4 and Endometrial Cancer. Among its related pathways are Mismatch repair and Colorectal Cancer Metastasis. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and single-stranded DNA binding. An important paralog of this gene is MSH6.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.
