Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.
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.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
The tetrameric structure of a casposase bound to DNA and its biochemical properties show how a transposase could have evolved to perform CRISPR-Cas spacer acquisition.
Combination of stem cell engineering and CRISPR technologies created a facile method to genetically manipulate macrophages, a multifunctional cell type that plays critical roles in immunity, cancer, and tissue homeostasis.
