Photoaffinity labelling with P3-(4-azidoanilido)uridine 5'-triphosphate identifies gpi3p as the UDP-GlcNAc-binding subunit of the enzyme that catalyses formation of GlcNAc-phosphatidylinositol, the first glycolipid intermediate in glycosylphosphatidylinositol synthesis.

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

Glycosylphosphatidylinositols (GPIs) are made by all eukaryotes. The first step in their synthesis is the transfer of GlcNAc from UDP-GlcNAc to phosphatidylinositol (PI). Four proteins in mammals and at least three in yeast make up a complex that carries out this reaction. Three of the proteins are highly conserved between yeast and mammals: the Gpi1 protein, the Pig-C/Gpi2 protein and the Pig-A/Gpi3 protein. The function of the individual subunits is not known, but of the three, the Pig-A/Gpi3 proteins resemble members of a large family of nucleotide-sugar-utilizing glycosyltransferases. To establish whether Gpi3p is the UDP-GlcNAc-binding subunit of the yeast GlcNAc-PI synthetic complex, we tested its ability to become cross-linked to the photoactivatable substrate analogue P(3)-(4-azidoanilido)-uridine 5'-triphosphate (AAUTP). We report that Gpi3p bearing the FLAG epitope at its C-terminus becomes cross-linked to AAUTP[alpha-(32)P], but that Gpi2p-FLAG does not. Furthermore, Gpi3p-FLAG expressed in Escherichia coli is also cross-linked. These results indicate that Gpi3p is the UDP-GlcNAc-binding and probable catalytic subunit of the GlcNAc-PI synthetic complex.
