Toward a genome-wide landscape of translational control

Abstract

Genome-wide analysis of translational control has taken strides in recent years owing to the advent of high-throughput technologies, including DNA microarrays and deep sequencing. Global studies have unraveled a principal role, among posttranscriptional mechanisms, for mRNAtranslation in determining protein levels in the cell. The impact of translational control in dynamic regulation of the proteome under different conditions is increasingly appreciated. Here we review genome-wide studies that use high-throughput techniques and bioinformatics to assess the role of mRNA translation in the regulation of protein levels; we also discuss howgenome-wide data onmRNA translation can be obtained, analyzed, and used to identify mechanisms of translational control. © 2013 Cold Spring Harbor Laboratory Press; all rights reserved.
