RNA complexes play significant roles in the regulation of gene expression through mechanisms such as:
RNA Interference (RNAi): Small interfering RNAs (siRNAs) and microRNAs (miRNAs) form complexes with proteins to degrade target mRNAs or inhibit their translation. Alternative Splicing: RNA-binding proteins regulate the splicing of pre-mRNA to produce multiple mRNA variants from a single gene. RNA Editing: Enzymes modify RNA sequences post-transcriptionally, affecting their function and stability.
