Summary: Enables ATP binding activity; ATP hydrolysis activity; and DNA secondary structure binding activity. Contributes to DNA binding activity. Involved in DNA metabolic process and silent mating-type cassette heterochromatin formation. Located in nuclear chromosome. Part of MutSalpha complex and MutSbeta complex. Used to study Lynch syndrome (multiple); cancer (multiple); and ovarian disease (multiple). Human ortholog(s) of this gene implicated in several diseases, including Lynch syndrome (multiple); gastrointestinal system cancer (multiple); lung cancer (multiple); mismatch repair cancer syndrome; and transitional cell carcinoma. Orthologous to human MSH2 (mutS homolog 2). [provided by Alliance of Genome Resources, Dec 2024]
