The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.

Interconnected RNA processing mechanisms ensure the fidelity of non-conventional mRNA splicing during the unfolded protein response.

The need for efficient pre-RNA splicing during early embryonic development of Drosophila indicates that the constraints imposed by the cell cycle are a force capable of driving changes in Eukaryotic gene architecture.

Surprising connections between gene architecture and splicing kinetics are illuminated using short, progressive metabolic labeling/RNA sequencing and novel computational modeling approaches in Drosophila cells.

Single-cell splicing of a conserved neuronal kinase is established by a combinatorial code of fate-determining transcription factors and neuronal RNA binding proteins, with different combinations in different neuron types.

A single human cell makes 10-100 transcriptional errors per second; these errors affect splicing and may influence the evolution of coding sequences.

Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.

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.

Ire1's RNase specificity and its cleavage sites coordination shape the evolutionary specialization of the unfolded protein response.

The structural model of hnRNP A1 shows that it can bind with both RRMs to RNA, which is shown to be relevant for the SMN2 exon 7 splicing mechanism in vivo.
