1 We found that polyamines stimulate the translation of histone acetyltransferases GCN5 and HAT1. Polyamines K(lysine) acetyltransferase 2A Mus musculus
2 Accordingly, GCN5- and HAT1-catalyzed acetylation of specific lysine residues on histones H3 and H4 was stimulated by polyamines. Polyamines K(lysine) acetyltransferase 2A Mus musculus
3 These results indicate that polyamines regulate gene expression by enhancing the expression of the histone acetyltransferases GCN5 and HAT1 at the level of translation. Polyamines K(lysine) acetyltransferase 2A Mus musculus
4 Mechanistically, polyamines enhanced the interaction of microRNA-7648-5p (miR-7648-5p) with the 5"-UTR of GCN5 mRNA, resulting in stimulation of translation due to the destabilization of the double-stranded RNA (dsRNA) between the 5"-UTR and the ORF of GCN5 mRNA. Polyamines K(lysine) acetyltransferase 2A Mus musculus
