Yeast Hsl7 is recognized as a homolog of human arginine methyltransferase 5 (PRMT5) and shows type II PRMT activity by forming symmetric dimethylarginine residues on histones. Previously, we reported that Hsl7 is responsible for in vivo symmetric dimethylation on histone H4 arginine 3 (H4R3me2s) in a transcriptionally repressed state, possibly in association with histone deacetylation by Rpd3. Here, we investigated the function of Hsl7 during cell cycle progression. We found that the accumulation of Hsl7-mediated H4R3me2s is maintained by the histone deacetylase Rpd3 during transcriptional repression and that the low level of H4R3me2s is required for proper asymmetric cell growth during cell division. Our results suggest that the hypoacetylated state of histones is connected to the function of Hsl7 in regulating properly polarized cell growth during cell division and provide new insight into the epigenetic modifications that are important for cell cycle morphogenesis checkpoint control based on the repressive histone crosstalk between symmetric arginine methylation of H4 and histone deacetylation.
