Messenger ribonucleic acid (mRNA) is an intermediate template in the process of protein production from a deoxyribonucleic acid (DNA) template. It offers the cell the means to control the production and destination of proteins in a complex, timely and transient way, and increases greatly the potential variation of protein isoforms. The number of molecules of any one mRNA species in a mammalian cell can vary from less than 1 to as many as 10000. In human cells, an average of about six copies of each mRNA are present per cell.

  • mRNA alternative splicing;
  • mRNA editing;
  • mRNA stability;
  • mRNA transport;
  • alternative polyadenylation site usage
