1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Cytoplasmic poly(A)-binding protein (PABP) C1 recruits different interacting partners to regulate mRNA fate. The majority of PABP-interacting proteins contain a PAM2 motif to mediate their interactions with PABPC1. However, little is known about the regulation of these interactions or the corresponding functional consequences. Through in silico analysis, we found that PAM2 motifs are generally embedded within an extended intrinsic disorder region (IDR) and are located next to cluster(s) of potential serine (Ser) or threonine (Thr) phosphorylation sites within the IDR. We hypothesized that phosphorylation at these Ser/Thr sites regulates the interactions between PAM2-containing proteins and PABPC1. In the present study, we have tested this hypothesis using complementary approaches to increase or decrease phosphorylation. The results indicate that changing the extent of phosphorylation of three PAM2-containing proteins (Tob2, Pan3, and Tnrc6c) alters their ability to interact with PABPC1. Results from experiments using phospho-blocking or phosphomimetic mutants in PAM2-containing proteins further support our hypothesis. Moreover, the phosphomimetic mutations appreciably affected the functions of these proteins in mRNA turnover and gene silencing. Taken together, these results provide a new framework for understanding the roles of intrinsically disordered proteins in the dynamic and signal-dependent control of cytoplasmic mRNA functions.
