Abstract excerpt
Mono-ubiquitylation of histone H2B correlates with transcriptional activation and is required for di- and trimethylation at Lys 4 on the histone H3 tail (H3K4) by the SET1/COMPASS methyltransferase complex through a poorly characterized trans-tail pathway. Here we show that mono-ubiquitylation of histone H2B promotes ubiquitylation at Lys 68 and Lys 69 of Swd2, the essential component of SET1/COMPASS in...
