ProteomicsU1 snRNP and RNA polymerase II interaction is predominantly mediated by Prp40 rather than U1-70K in yeast
Transcription and splicing are coupled both temporally and physically. A previous cryo-EM structure of the human U1 snRNP and RNA polymerase pol II complex has shown that U1 snRNP uses predominantly the RRM domain of U1-70K to directly interact with the RPB2 subunit of pol II. However, residues on U...

TranscriptomicsThe conserved Prp40 WW domains facilitate non-canonical intron splicing via bridging 5'-splice-site and branch-site interaction
Precise regulation of molecular interactions is essential for the proper execution of cellular pathways. In pre-mRNA splicing, the spliceosome must accurately process introns containing both canonical and non-canonical splice-site sequences, the latter often requiring additional regulatory mechanism...

TranscriptomicsSpliceosome-Mediated-Decay (SMD) regulates expression of non-intronic genes in budding yeast
Purpose: The goals of this study were to determine whether the spliceosome interacts with non-intronic mRNAs Methods: RNAseq was performed on RNA that immunoprecipitated with the yeast SMD1 protein. Tandem-affinity-purified RNAs were extracted and RNAseq libraries were generated using the EpiCentre...
