H3.3 G34W stimulates NSD1

New publication in "Biochimie"

The H3.3 G34W mutation has been observed in 90% of the patients affected by giant cell tumor of bone (GCTB). It had been shown to reduce the activity of the SETD2 H3K36 protein lysine methyltransferase (PKMT) and lead to genome wide changes in epigenome modifications including a global reduction in DNA methylation. In this publication, we show that H3.3 G34W unexpectedly stimulates the activity of the NSD1 PKMT strongly. The potential downstream effects of the G34W induced hyperactivity of NSD1 on DNA methylation, H3K27me3, histone acetylation and splicing are discussed.
