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

Regulation of the magnitude, duration, and localization of G protein-coupled receptor (GPCR) signaling responses is controlled by desensitization, internalization, and downregulation of the activated receptor. Desensitization is initiated by the phosphorylation of the activated receptor by GPCR kinases (GRKs) and the binding of the adaptor protein arrestin. In addition to phosphorylating activated GPCRs, GRKs have been shown to phosphorylate a variety of additional substrates. An in vitro screen for novel GRK substrates revealed Hsp70 interacting protein (Hip) as a substrate. GRK5, but not GRK2, bound to and stoichiometrically phosphorylated Hip in vitro. The primary binding domain of GRK5 was mapped to residues 303-319 on Hip, while the major site of phosphorylation was identified to be Ser-346. GRK5 also bound to and phosphorylated Hip on Ser-346 in cells. While Hip was previously implicated in chemokine receptor trafficking, we found that the phosphorylation of Ser-346 was required for proper agonist-induced internalization of the chemokine receptor CXCR4. Taken together, Hip has been identified as a novel substrate of GRK5 in vitro and in cells, and phosphorylation of Hip by GRK5 plays a role in modulating CXCR4 internalization.
