Puromycin is a well-known antibiotic that is used to study the mechanism of protein synthesis and to monitor ribosome activity due to its incorporation into nascent peptide chains. However, puromycin effects outside the ribosome catalytic core remain unexplored. Here, we developed two analogues (3PB and 3PC) of the 3'-end of tyrosylated-tRNA that can efficiently interact with several proteins associated with ribosomes.

Ribosome profiling, or Ribo-seq, is based on large-scale sequencing of RNA fragments protected from nuclease digestion by ribosomes. Thanks to its unique ability to provide positional information about ribosomes flowing along transcripts, this method can be used to shed light on mechanistic aspects of translation. However, current Ribo-seq approaches lack the ability to distinguish between fragments protected by either ribosomes in active translation or inactive ribosomes.

RNA binding motif protein 10 (RBM10) is a regulator of alternative splicing in apoptosis and inflammation. We discovered a splicing-independent function of RBM10 critical for the regulation of heart failure (HF). RBM10 is enriched in the heart and associates with Star-PAP (TUT1) to control the expression and 3' end processing of cardiac mRNAs.

Almost all eukaryotic mRNAs have a poly (A) tail at the 3'-end. Canonical PAPs (PAPα/γ) polyadenylate nuclear pre-mRNAs. The recent identification of the non-canonical Star-PAP revealed specificity of nuclear PAPs for pre-mRNAs, yet the mechanism how Star-PAP selects mRNA targets is still elusive.
