摘要
Genetic information flows from DNA to protein through RNA in the central dogma.Different RNA species are known to accomplish essential tasks of protein encoding(mRNAs),amino acid loading(tRNAs),and translation machinery assembly(rRNAs).However,on top of these well-known roles,RNAs are central to various cellular regulatory pathways.Here we summarize newly emerging regulatory functions of RNA,specifically focusing on regulations through RNA modifications,RNP granules,and chromatin-associated regulatory RNA.In addition to being an essential building block of the central dogma,RNA can be critical to the regulation of many cellular processes.
