Abstract
The ability of cells to grow and divide, differentiate and function, and even senesce is dependent on the fine-tuning of both gene and protein expression. Protein concentration in the cell is regulated not only at the transcriptional and post-translational levels, but also at the level of translation. Ribosomes, the molecular machines behind translation, were once considered to be an invariant driving force behind protein expression. However, studies over the past decade paint a rather different picture; namely, that ribosomes constitute an additional layer of regulatory control that might define which subsets of mRNAs are translated, to what extent, and to what purpose. Recent works summarized herein directly implicate ribosome heterogeneity and, in particular, ribosomal protein (RP) paralog specificity in regulating mRNA translation and control of the cellular translatome.
