Predicted to enable several functions, including DNA binding activity; chromatin binding activity; and methylated histone binding activity. Predicted to contribute to several functions, including DNA binding activity; MutLalpha complex binding activity; and adenyl ribonucleotide binding activity. Involved in mismatch repair and spermatogenesis. Predicted to be located in several cellular components, including Golgi apparatus; chromatin; and nucleoplasm. Predicted to be part of MutSalpha complex. Used to study hereditary nonpolyposis colorectal cancer type 5. Human ortholog(s) of this gene implicated in Lynch syndrome; colorectal carcinoma; endometrial cancer; hereditary nonpolyposis colorectal cancer type 5; and mismatch repair cancer syndrome. Orthologous to human MSH6 (mutS homolog 6). [provided by Alliance of Genome Resources, Apr 2022]
