CARM1 functions as a transcriptional coactivator for p53 in an ordered, cooperative manner with PRMT1 and p300 on chromatin templates, requiring direct interactions with p53 and obligatory histone modifications (H3R17me2 and H4R3me2). ChIP confirmed ordered accumulation of these coactivators and histone marks on the GADD45 gene after p53 activation. |

CARM1 methylates histone H3R17 in an ordered fashion downstream of CBP-mediated acetylation of H3K18 and H3K23 at the estrogen-responsive pS2 promoter. Acetylation at K18/K23, but not K14, tethers recombinant CARM1 to the H3 tail and enhances its methyltransferase activity, revealing crosstalk between lysine acetylation and arginine methylation. |

CARM1 stability is regulated by SKP2-containing SCF E3 ubiquitin ligase in the nucleus under nutrient-rich conditions. Upon nutrient starvation, AMPK-dependent phosphorylation of FOXO3a represses SKP2 transcription, stabilizing CARM1 protein, which then increases H3R17 dimethylation and acts as transcriptional co-activator for autophagy-related and lysosomal genes via TFEB. |
