Abstract
EXOSC10 is a conserved 3'-5' exoribonuclease involved in processing ribosomal RNAs and degrading coding and noncoding transcripts as a catalytic subunit of the nuclear RNA exosome and in cooperation with cofactors. The protein is posttranslationally modified and shuttles between the nucleolus and the nucleus in response to oxygen deprivation in a process that involves sumoylation. EXOSC10 is of medical interest because its activity is inhibited by the anticancer drug 5-fluorouracil, which interferes with DNA replication and RNA-dependent processes. Moreover, high expression of EXOSC10 in certain somatic tumors is associated with patient survival. We discuss global and tissue-specific deletion experiments in the mouse, assess the protein's clinical relevance as a prognostic cancer biomarker in the context of human genomics data for normal versus malignant tissues, and explore EXOSC10's transcriptional regulatory network.
期刊介绍：
RNA is a monthly journal which provides rapid publication of significant original research in all areas of RNA structure and function in eukaryotic, prokaryotic, and viral systems. It covers a broad range of subjects in RNA research, including: structural analysis by biochemical or biophysical means; mRNA structure, function and biogenesis; alternative processing: cis-acting elements and trans-acting factors; ribosome structure and function; translational control; RNA catalysis; tRNA structure, function, biogenesis and identity; RNA editing; rRNA structure, function and biogenesis; RNA transport and localization; regulatory RNAs; large and small RNP structure, function and biogenesis; viral RNA metabolism; RNA stability and turnover; in vitro evolution; and RNA chemistry.
