Predicted to enable histone-lysine N-methyltransferase activity and transcription corepressor activity. Predicted to be involved in histone lysine methylation; positive regulation of myoblast differentiation; and positive regulation of myotube differentiation. Predicted to act upstream of or within several processes, including chromatin remodeling; negative regulation of transcription, DNA-templated; and skeletal muscle cell differentiation. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Orthologous to human SMYD1 (SET and MYND domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
