Outline of Final Research Achievements

Wilms’ tumor 1-associating protein (WTAP) is a putative splicing regulator which is required for mouse early embryo development and cell cycle progression. We previously isolated the proteins which interact with WTAP, including VIRILIZER, CBLL1, KIAA0853, RBM15, BCLAF1, THRAP3 and general splicing regulators.To identify the alternative RNA splicing regulated by WTAP protein complex, we performed high-throughput mRNA sequencing using WTAP knockdown cells. Interestingly, WTAP regulates alternative splicing of histone H4 Lys 20 methyltransferases SUV420H1 and SUV420H2 by promoting a production of the truncated isoforms, leading to a change in the global H4K20 methylation level.
