Project description:Ribosome small subunit (SSU) is assembled by the SSU processome which contains approximately 70 non-ribosomal protein factors. The biochemical mechanism for the SSU processome in 18S rRNA processing and maturation has been extensively studied, however, how the SSU processome components enter to the nucleolus has not been systematically investigated. Here we checked the nucleolar localization of 50 human SSU processome components and find that UTP3 and other 24 proteins enter to the nucleolus autonomously. For the remaining 25 proteins we find that UTP3/SAS10 assists the nucleolar localization of five proteins, namely MPP10, UTP25, EMG1 and two UTP-B components UTP12 and UTP13, and this ferry function of UTP3 is conserved in zebrafish. We also find that knockdown of human UTP3 impairs the cleavage at A0-site while loss-of-function of either utp3/sas10 or utp13/tbl3 in zebrafish causes an accumulation of the processed products containing the 5′ETS, supporting the crucial role of UTP3 in mediating the 5′ETS processing and degradation. Moreover, UTP3 directly interacts with and delivers EXOSC10 into the nucleolus, suggesting that UTP3 may play a direct role in recruiting the nuclear exosome to the SSU processome for degradation of the processed 5′ETS. These findings lay the ground for studying the mechanism of cytoplasm-to-nucleolus trafficking of the SSU processome components and the multifaceted roles of UTP3 during pre-rRNA processing.

Project description:Iron-rich pelagic aggregates (iron snow) were collected directly onto silicate glass filters using an electronic water pump installed below the redoxcline. RNA was extracted and library preparation was done using the NEBNext Ultra II directional RNA library prep kit for Illumina. Data was demultiplied by GATC sequencing company and adaptor was trimmed by Trimgalore. After trimming, data was processed quality control by sickle and mRNA/rRNA sequences were sorted by SortmeRNA. mRNA sequences were blast against NCBI-non redundant protein database and the outputs were meganized in MEGAN to do functional analysis. rRNA sequences were further sorted against bacterial/archeal 16S rRNA, eukaryotic 18S rRNA and 10,000 rRNA sequences of bacterial 16S rRNA, eukaryotic 18S rRNA were subset to do taxonomy analysis.

Project description:Purpose: Pre-ribosomal RNA is cleaved at defined sites to release the mature ribosomal RNAs, but the functions of many ribosome biogenesis factors involved in 18S rRNA release are not known. We apply an in vivo cross-linking technique coupled with deep sequencing (CRAC) that captures transcriptome-wide interactions between the yeast PIN domain protein Utp23 and its targets in a living cell. Methods: We apply CRAC to an HTP-tagged Utp23 protein (HTP: His6 - TEV cleavage site - two copies of the z-domain of Protein A) in budding yeast. At least two independent experiments were performed and analysed separately. A non-tagged yeast strain was also used as a negative control. Results: We found that yeast Utp23 UV-crosslinked in vivo to the snR30 snoRNA and to the eukaryotic-specific expansion segment 6 (ES6) in the 18S rRNA. Conclusion: According to our crosslinking data, Utp23 is perfectly positioned to coordinate release of the snR30 snoRNA from the 18S ES6 region.
