Predicted to enable several functions, including RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; cation binding activity; and histone methyltransferase activity (H3-K9 specific). Predicted to be involved in several processes, including chromatin organization; histone H3-K9 methylation; and negative regulation of circadian rhythm. Predicted to act upstream of or within several processes, including cellular response to hypoxia; histone H3-K9 methylation; and male meiotic nuclear division. Predicted to be located in heterochromatin. Predicted to be active in nucleus. Orthologous to human SUV39H2 (SUV39H2 histone lysine methyltransferase).
