Regulation by alternative splicing

Regulation by alternative splicing
In Expression of Gene : Protein Synthesis 3.  RNA Processing (RNA Splicing, RNA Editing and Ribozymes), we discussed the phenomenon of alternative splicing, which means that a transcript or a precursor mRNA may undergo one of the several paths of alternative splicing, so that the same transcript may lead to the synthesis of different protein 'isoforms' in time and space. This mechanism has been shown to be widespread in organisms ranging from viruses to mammals and is used for regulation of gene expression at the post-transcriptional level.
