Quantitative proteomics of Col and AtPABs mutant


ABSTRACT: To determine if the difference in AtPAB-binding efficiency affects protein levels, we performed the Tandem Mass Tag (TMT)-based quantitative proteomics on the two-week old seedlings of Col and the mut, respectively.

<h4>Background</h4>Polyadenylation plays a key role in producing mature mRNAs in eukaryotes. It is widely believed that the poly(A)-binding proteins (PABs) uniformly bind to poly(A)-tailed mRNAs, regulating their stability and translational efficiency.<h4>Results</h4>We observe that the homozygous triple mutant of broadly expressed Arabidopsis thaliana PABs, AtPAB2, AtPAB4, and AtPAB8, is embryonic lethal. To understand the molecular basis, we characterize the RNA-binding landscape of these PABs  ...[more]
