RNA binding proteins (RBPs) interact with primary, precursor, and mature microRNAs (miRs) to influence mature miR levels, which in turn affect critical aspects of human development and disease. To understand how RBPs contribute to miR biogenesis, we analyzed human enhanced UV crosslinking followed by immunoprecipitation (eCLIP) datasets for 126 RBPs to discover miR-encoding genomic loci that are statistically enriched for RBP binding. We find that 92% of RBPs interact directly with at least one miR locus, and that some interactions are cell line specific despite expression of the miR locus in both cell lines evaluated. We validated that ILF3 and BUD13 directly interact with and stabilize miR-144 and that BUD13 suppresses mir-210 processing to the mature species. We also observed that DDX3X regulates primary miR-20a, while LARP4 stabilizes precursor mir-210. Our approach to identifying regulators of miR loci can be applied to any user-defined RNA annotation, thereby guiding the discovery of uncharacterized regulators of RNA processing.

View all literature mentionsSoftware package for differential gene expression analysis based on the negative binomial distribution. Used for analyzing RNA-seq data for differential analysis of count data, using shrinkage estimation for dispersions and fold changes to improve stability and interpretability of estimates.
View all literature mentionsA powerful toolset for genome arithmetic allowing one to address common genomics tasks such as finding feature overlaps and computing coverage. Bedtools allows one to intersect, merge, count, complement, and shuffle genomic intervals from multiple files in widely-used genomic file formats such as BAM, BED, GFF/GTF, VCF. While each individual tool is designed to do a relatively simple task (e.g., intersect two interval files), quite sophisticated analyses can be conducted by combining multiple bedtools operations on the UNIX command line.
