We developed a mass spectrometry-compatible subcellular fractionation protocol. This method involves separating cells into cytoplasmic, organellar, and nuclear fractions without ultracentrifugation.
Chinese hamster ovary (CHO) cells have been widely employed for production of recombinant proteins (RP) for research and therapeutic purposes. Indeed, this expression system was used for production of most of approved antibodies (84%) in 2015-2018 period. The success of this cell line for RP product...
Protein lactylation is a novel post-translational modification (PTM) involved in many important physiological processes such as macrophage polarization, immune regulation and tumour cell growth. However, most studies to date have focused on the function of lactylation on histones, and little is know...
We isolated whole embryo, nuclear, and cytoplasmic lysates from Drosophila embryos during early and late embryogenesis In Drosophila melanogaster, cell-type specification during early nervous system development requires precise regulation of gene expression in time and space. To investigate the gene...
We detect the small RNAs subcellular distribution in breast cancer cell lines MCF-7 and MDA-MB-231, and normal cell line MCF-10A. Each cell line, we detected the nuclear and cytoplasmic small RNAs expression intensity; and then we could get the nuclear-cytoplasmic-ratio.
The synthesis of snake venom proteins is subjected to finely regulated processes in the specialized secretory epithelium within the venom gland. Such processes occur within a defined time frame in the cell and at specific cellular locations. Thus, the determination of subcellular proteomes allows th...
Mapping the subcellular proteome using a differential fractionation and an orthogonal nycodenz fractionation combined with quantitative mass spectrometry using isobaric labeling (TMT) in MS2
We report a new method which combines subcellular fractionation to advance sequencing technique iCLIP. In this way we identified the spectrum of interactions of two SR-proteins (SRSF3 and SRSF7) to their target RNAs in different subcellular compartments
