Cracking the MiRISC Code: An Investiagtion in to Charactersing a ‘Hidden Code’ within MicroRNA Silencing Biology!

Tyson Sharp  Cracking the MiRISC Code

MicroRNA-mediated silencing in mammalians regulates almost all fundamental cellular and biological processes. Central to this are four Argonaute (AGO) proteins, which are thought to have overlapping functions. However, our data and this exciting project will address how their redundancy is controlled by the association of LIMD1 family proteins (LIMD1, Ajuba and WTIP (LAW)). AGOs are part of the miRNA induced silencing complexes (miRISC), which also contains TNRC6 family proteins. The specific combinations of AGO/LAW/TNRC6 and the conditions/cell contexts (‘miRISC code’) that give rise to correct control of gene expression will be characterized in this novel study.
