Changshou Wang#, Lin Xu#, Chen Du#, Hao Yun#, Keyun Wang#, Hui Liu, Mingliang Ye*, Jing Fan*, Yu Zhou* and Hong Cheng*. CDK11 requires a critical activator SAP30BP to regulate pre‐mRNA splicing. EMBO J (2023)42: e114051. https://doi.org/10.15252/embj.2023114051

CDK11 is an emerging druggable target for cancer therapy due to its prevalent roles in phosphorylating critical transcription and splicing factors and in facilitating cell cycle progression in cancer cells. Like other cyclin‐dependent kinases, CDK11 requires its cognate cyclin, cyclin L1 or cyclin L2, for activation. However, little is known about how CDK...

Ting Shan#, Feiyan Liu#, Miaomiao Wen#, Zonggui Chen, Shaopeng Li, Yafen Wang, Hong Cheng, Yu Zhou*. m6A modification negatively regulates translation by switching mRNA from polysome to P-body via IGF2BP3. Molecular Cell S1097276523009115 (2023) doi:10.1016/j.molcel.2023.10.040.

In the cytoplasm, mRNAs are dynamically partitioned into translating and non-translating pools, but the mechanism for this regulation has largely remained elusive. Here, we report that m6A regulates mRNA partitioning between polysome and P-body where a pool of non-translating mRNAs resides. By quantifying the m6A level of polysomal and cytoplasmic mRNAs w...

The polyA tail of mRNAs is important for many aspects of RNA metabolism. However, whether and how it regulates pre‐mRNA splicing is still unknown. Here, we report that the polyA tail acts as a splicing enhancer for the last intron via the nuclear polyA binding protein PABPN1 in HeLa cells. PABPN1‐depletion induces the retention of a group of introns with ...

The processing of the proximal and distal poly(A) sites in alternative polyadenylation (APA) has long been thought to independently occur on pre-mRNAs during transcription. However, a recent study by our groups demonstrated that the proximal sites for many genes could be activated sequentially following the distal ones, suggesting a multi-cleavage-same-tr...

A U2-snRNP–independent role of SF3b in promoting mRNA export. Proceedings of the National Academy of Sciences, 116(16):7837–7846, April 2019.

To ensure efficient and accurate gene expression, pre-mRNA processing and mRNA export need to be balanced. However, how this balance is ensured remains largely unclear. Here, we found that SF3b, a component of U2 snRNP that participates in splicing and 3′ processing of pre-mRNAs, interacts with the key mRNA export adaptor THO in vivo and in vitro. Depleti...

New data identify a parallel mechanism for ALYREF also linking 3'-end processing to nuclear export of non-polyadenylated, replication-dependent histone mRNAs. ALYREF prevalently binds to a 3' region of histone mRNAs in an SLBP-depend...

The Augmented R-Loop Is a Unifying Mechanism for Myelodysplastic Syndromes Induced by High-Risk Splicing Factor Mutations. Molecular Cell, 69(3):412–425.e6, February 2018.

Mutations in several general pre-mRNA splicing factors have been linked to myelodysplastic syndromes (MDSs) and solid tumors. These mutations have generally been assumed to cause disease by the resultant splicing defects, but different mutations appear to induce distinct splicing defects, raising the possibility that an alternative common mechanism is inv...
