The protein-metabolite interactome remains understudied. We previously developed a co-fractionation mass-spectrometry-based approach called PROMIS to address this gap. PROMIS relies on size separation chromatography of protein-metabolite complexes from lysates, followed by proteomics and metabolomic...
For data-independent acquisition by means of sequential window acquisition of all theoretical fragment ion spectra (SWATH), a reference library of data-dependent acquisition (DDA) runs is typically used to correlate the quantitative data from the fragment ion spectra with peptide identifications. Th...
In this study, we employed a special size fractionation and cDNA library construction method followed by 454 deep sequencing to systematically profile rice intermediate-size ncRNAs. Our analysis resulted in the identification of 1349 ncRNAs in total, including 754 novel ncRNAs of an unknown function...
Human hepatocytes differ in gene expression and function across the hexagonal lobules of the tissue microarchitecture, a phenomenon referred to as liver zonation. Hepatocytes also display intra-lobular differences in cell size, but to what extent zonal expression and function correlate with cell siz...
Epigenetic modifications of chromatin serve an important role in regulating the expression and accessibility of genomic DNA. We report here a genomewide approach for fractionating yeast chromatin into two functionally distinct parts, one containing RNA polymerase II transcribed sequences, and the ot...
