Research Abstract

Degradation of mRNA plays an essential role in regulation of gene expression in all organisms. Defects in this process lead to potentially fatal defects. mRNA degradation is mediated by the concerted action of several ribonucleases including β-CASP family proteins. This study revealed the mechanism of RNA degradation by β-CASP family proteins and found a novel pathway that involves these proteins.
