In the single-celled eukaryote Entamoeba histolytica , we have identified a population of small RNAs of 27 nt size that ( i ) ... | Regulation of gene expression can occur via multiple conserved pathways . One such mechanism is mediated by RNA molecules of about 21–24 nucleotides ( called small RNAs ) , which can affect rates of RNA degradation or protein production .

Metazoan genomes encode hundreds of RNA-binding proteins ( RBPs ) . These proteins regulate post-transcriptional gene expression and have critical roles in numerous cellular processes including mRNA splicing , export , stability and translation . Despite their ubiquity and importance , the binding preferences for most ... | Many disease-associated mutations do not change the protein sequence of genes; instead they change the instructions on how a gene's mRNA transcript should be processed .
