Predicted to enable histone binding activity and nucleosome binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; early conceptus; genitourinary system; limb; and maxillary process. Human ortholog(s) of this gene implicated in acute monocytic leukemia and acute myeloid leukemia. Orthologous to human MLLT10 (MLLT10 histone lysine methyltransferase DOT1L cofactor).
