Cytoplasmic Drosha activity generated by alternative splicing
RNase III enzyme Drosha interacts with DGCR8 to form the Microprocessor, initiating canonical microRNA (miRNA) maturation in the nucleus. Here, we re-evaluated where Drosha functions in cells using Drosha and/or DGCR8 knock out (KO) cells and cleavage reporters. Interestingly, a truncated Drosha mutant located exclusively in the cytoplasm cleaved pri-miRNA effectively in a DGCR8-dependent manne...
متن کاملAlternative splicing affects the subcellular localization of Drosha
The RNase III enzyme Drosha is a key factor in microRNA (miRNA) biogenesis and as such indispensable for cellular homeostasis and developmental processes. Together with its co-factor DGCR8, it converts the primary transcript (pri-miRNA) into the precursor hairpin (pre-miRNA) in the nucleus. While the middle and the C-terminal domain are crucial for pri-miRNA processing and DGCR8 binding, the fu...
متن کاملDrosha Promotes Splicing of a Pre-microRNA-like Alternative Exon
The ribonuclease III enzyme Drosha has a central role in the biogenesis of microRNA (miRNA) by binding and cleaving hairpin structures in primary RNA transcripts into precursor miRNAs (pre-miRNAs). Many miRNA genes are located within protein-coding host genes and cleaved by Drosha in a manner that is coincident with splicing of introns by the spliceosome. The close proximity of splicing and pre...
متن کاملRole of Aberrant Alternative Splicing in Cancer
Alternative splicing can alter genome sequence and as a consequence, many genes change to oncogenes. This event can also affect protein function and diversity. The growing number of study elucidate the pathological influence of impaired alternative splicing events on numerous disease including cancer. Here, we would like to highlight the significant role of alternative splicing in cancer biolog...
متن کاملLeveraging transcript quantification for fast computation of alternative splicing profiles.
Alternative splicing plays an essential role in many cellular processes and bears major relevance in the understanding of multiple diseases, including cancer. High-throughput RNA sequencing allows genome-wide analyses of splicing across multiple conditions. However, the increasing number of available data sets represents a major challenge in terms of computation time and storage requirements. W...
