Hinokiflavone is identified as a splicing modulator that blocks progression from spliceosome complex A to complex B and inhibits SUMO protease SENP1, causing hyper-SUMOylation affecting 6 U2 snRNP proteins.
Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.
Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
The exon junction complex regulates the cell polarity determinant Discs large 1, which acts independently from its role in cell polarity to protect Dishevelled protein from lysosomal degradation in Wingless/Wnt signaling.
Inactivation of a multifunctional RNA-binding protein can lead to the acquisition of pro-metastatic phenotypes, possibly by stabilizing large-scale transcriptomic changes that provide a selective advantage during cancer progression.
