ProteomicsCoordination of nuclear RNA processing by speckle-localized kinase TAOK2
Nuclear speckles are membraneless organelles that act as active splicing hubs especially at sites of high transcription; emerging views of this dynamic subnuclear structure place it as a hub of RNA processing from transcription to export. To manage a complex microcosm of RNA metabolism, nuclear spec...

TranscriptomicsCytoplasmic Assembly and Selective Nuclear Import of Arabidopsis ARGONAUTE4/siRNA Complexes
Here we profiled small RNAs from whole cell, cytoplasmic and nuclear extracts from three-week-old Arabidopsis seedlings. We unexpectedly found that nuclear functional hc-siRNAs are predominantly present in the cytoplasm. Samples from Arabidopsis thaliana whole cell, cytoplasmic and nuclear extract...

TranscriptomicsBiochemical fractionation of HEK293 nuclei and RNA-seq of chromatin-associated and soluble-nuclear RNA
Biochemical fractionation of HEK293 nuclei and RNA-seq of chromatin-associated and soluble-nuclear RNA. Nuclei from three biological replicates were isolated by detergent lysis, fractionated, then three chromatin and three soluble RNA samples were converted to cDNA using Illumina TruSeq stranded pro...

TranscriptomicsGlobal analysis of the nuclear processing of unspliced U12-type introns by the exosome
we analyzed globally the effect of exosome processing on the nuclear pre-mRNA transcripts by inactivating either the RRP41 or DIS3 subunit of the exosome. Using SOLiD RNA sequencing technology, we report 30-120 million mapped cellular compartment specific reads per sample allowing the detection of u...

TranscriptomicsMitochondrial unfolded protein response controls matrix pre-RNA processing and translation
The mitochondrial matrix is unique in that it must integrate folding and assembly of proteins derived from nuclear and mitochondrial genomes. In C. elegans, the mitochondrial unfolded protein response (UPRmt) senses matrix protein misfolding and induces a program of nuclear gene expression, includin...

ProteomicsIdentification of mRNA processing complexes bound to histone H2A.2 3’ untranslated region
Processing of 3’ untranslated region (3’-UTR) of precursor messenger RNAs (pre-mRNA) is a fundamental step in mRNA maturation, where the mRNA transcript is cleaved at a specific site, located downstream the open reading frame of the encoded gene. The position of the cleavage site is determined by ci...

TranscriptomicsAlternative RNA processing events in a double NSR mutant Arabidopsis
We analyze the effect of a double deletion mutant for alternative-splicing regulators nsra and nsrb (Nuclear Speckle RNA binding proteins), on the Arabidopsis thaliana transcriptome. RNA-seq experiments (polyA+ RNA) in triplicates for each condition WT and nsrab mutants.

ProteomicsMolecular basis for the interaction of intrinsically disordered proteins with nuclear PIP2 compartments
Phosphatidylinositol 4,5 bisphosphate (PIP2) is the most abundant eukaryotic nuclear phosphoinositide. PIP2 is found in the nuclear speckles (NS), nucleoli (NL), and nuclear lipid islets (NLIs) and participates in the RNA polymerase II (Pol2) transcription. The formation of phase-separated nuclear s...
