Predicted to enable RNA binding activity. Predicted to contribute to histone methyltransferase activity (H3-K4 specific). Predicted to be involved in histone H3-K4 dimethylation; histone H3-K4 monomethylation; and histone H3-K4 trimethylation. Predicted to be located in nucleoplasm. Predicted to be part of Set1C/COMPASS complex. Orthologous to human SETD1B (SET domain containing 1B, histone lysine methyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
