GSE GEOThe LncRNA NEAT1 Nests RNA Binding Proteins and the Microprocessor to Globally Enhance Pri-miRNA Processing
Relations
Summary
MicroRNA biogenesis is known to be modulated by a variety of RNA binding proteins (RBPs), but in most cases, individual RBPs appear to influence the processing of a small number of selective targets. We herein report binding of the NONO/PSF heterodimer to hundreds of expressed pri-miRNAs in HeLa cells to globally enhance pri-miRNA processing by the Drosha/DGCR8 Microprocessor. As NONO/PSF are key components of paraspeckles organized by the lncRNA NEAT1, we find that NEAT1 also has profound effects on global pri-miRNA processing. Mechanistic dissection reveals that NEAT1 broadly interacts with NONO/PSF as well as many other RBPs, and that multiple RNA segments in NEAT1, including a âpseudo pri-miRNAâ near its 3â end, help attract the Microprocessor. These findings suggest a bird nest model for a large lncRNA to orchestrate efficient processing of an entire class of small RNAs in the nucleus.we used small RNA-seq to identify miRNA level in response to secific knockdowns relative to siGFP treatment control
Overall Design
We profiled the miRNAs expression levels under conditions including siGFP(control), siNEAT1, siNEAT1_V2, siNONO, siPSF and siPSPC1 through small RNA-seq respectively. And we also examined the in vivo interactions between NONO/PSF and RNA through CLIP-seq.
Analysis (6 steps)
View Data Processing- For each CLIP-seq read, the first 4nt index sequence was extracted and the 3'-adaptor sequence CTCGTATGCCGTCTTCTGCTTG was removed with program cutadapt (version 1.8.3).
- The reads with at least 18nt were mapped to the human genome (hg19) by Bowtie (version 1.1.1) with parameters '-l25 -n2 -k1 -m10 -e 200 --best --strata'.
- For each small RNA-seq read, the firsst 5nt NNNTC was extracted and 3' adaptor sequence 'NNCTCGTATGCCGTCTTCTGCTTG' was removed with program cutadapt (version 1.8.3).
- The target insert sequences were required to be at least 16 nt.
- The filtered reads were mapped to the genome genome (hg19) by Bowtie (version 1.1.1) with parameters '-n 0 -e 80 -l 18 -a -m 5 --best --strata'.
- The mapped reads were used to generate the genomic coverage profiles in bigWig format with programs genomeCoverageBed (bedtools version 2.24) and samtools (version 0.1.19).
