Predicted to enable several functions, including lysine-acetylated histone binding activity; protein homodimerization activity; and protein methyltransferase activity. Involved in membrane depolarization and response to potassium ion. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of MLL1 complex. Human ortholog(s) of this gene implicated in acute myeloid leukemia; cervical cancer; mixed phenotype acute leukemia; and non-Hodgkin lymphoma. Orthologous to human KMT2A (lysine methyltransferase 2A). [provided by Alliance of Genome Resources, Apr 2022]
