Predicted to enable several functions, including ATP hydrolysis activity; chromatin binding activity; and guanine/thymine mispair binding activity. Predicted to contribute to MutSalpha complex binding activity and single-stranded DNA binding activity. Involved in several processes, including response to hypoxia; response to toxic substance; and spermatogenesis. Located in synaptonemal complex. Used to study lung carcinoma. Human ortholog(s) of this gene implicated in Lynch syndrome (multiple); gastrointestinal system cancer (multiple); lung cancer; mismatch repair cancer syndrome; and sporadic breast cancer. Orthologous to human MLH1 (mutL homolog 1). [provided by Alliance of Genome Resources, Apr 2022]
