Cytoplasmic regulation of mRNAs during early vertebrate development: Mechanisms and roles of RNA-protein interactions
Lead Research Organisation:
MRC Human Genetics Unit
Abstract
The control of protein production in the body is vital for health. All proteins are products of particular genes and these have to be turned on at the right times, places and in the right amount to ensure proper cell function. This process is called gene expression. One level at which gene expression is controlled is called translation, in which mRNA templates copied from genes are used as instructions to build proteins. Recent research has shown that when the processes that control translation fail, it can lead to a wide variety of human diseases including cancers, neurological, metabolic and reproductive disorders.|By focusing on related families of translational regulators, we aim to discover the general mechanisms by which these classes of proteins function and also to increase our knowledge of pathways leading to a variety of genetic disorders. This may ultimately lead to better treatment.
Technical Summary
The overall scientific aim of this program is to understand the fundamental mechanisms and roles of regulating mRNA translation. Recent data suggests that 40-60% of vertebrate mRNAs are controlled at the level of translation and that breakdowns in this process can lead to disease. Despite this, the roles and underlying mechanisms of translational control are poorly understood. Thus dissecting their contribution to normal biology and human disease is a priority. We focus on three basic questions regarding RNA-protein complexes that regulate translation of specific mRNAs. Firstly, the identification of trans-acting factors that regulate translation. Secondly, the mechanisms by which these RNA-protein complexes function. Thirdly, what are the roles of these RNA-protein complexes in biological processes such as development and in disease.
