GCN2 suppresses TOP mRNA translation via LARP1
With the rapid growth of synthetic messenger RNA (mRNA)-based therapeutics and vaccines, the development of analytical tools for characterization of long, complex RNAs has become essential. Tandem liquid chromatography-mass spectrometry (LC-MS/MS) permits direct assessment of the mRNA primary sequen...

Lsp2 links mTORC1 to TOP mRNA translation and lifespan in Drosophila
Translational regulation is of paramount importance for proteome remodeling during stem cell differentiation both at the global and transcript-specific levels. In this study, we characterized translational remodeling during hepatogenic differentiation of induced pluripotent stem cells (iPSCs) by pol...

Lsp2 links mTORC1 to TOP mRNA translation and lifespan in Drosophila
La-related protein 1 (LARP1) has been identified as a key translational inhibitor of terminal oligopyrimidine tract (TOP) mRNAs downstream of the nutrient sensing protein kinase complex, mTORC1. LARP1 exerts this inhibitory effect on TOP mRNA translation by binding to the mRNA cap and the adjacent 5...

mTOR- and LARP1-dependent regulation of TOP mRNA poly(A) tail and ribosome loading [polysome fractionation]
Diurnal oscillations of gene expression are a hallmark of rhythmic physiology across most living organisms. Such oscillations are controlled by the interplay between the circadian clock and feeding rhythms. While rhythmic mRNA accumulation has been extensively studied, comparatively less is known ab...
