Abstract

Getting Gametes Together: Despite decades of research, the molecular basis of sperm-egg recognition in mammals remains unresolved. Models in which a glycan ligand in the zona pellucida (ZP) surrounding ovulated eggs binds to a sperm surface receptor have been widely embraced. A more recent model proposes that the cleavage status of a ZP protein, ZP2, renders the structure of the zona matrix either permissive or nonpermissive for sperm binding. Gahlay et al. (p. 216 ) tested predictions of each model by replacing endogenous zona proteins with either a mutant form of ZP2 that could not be cleaved or of ZP3 that lacked O glycan attachment sites. Sperm-egg recognition depended on the cleavage status of ZP2 rather than on glycan ligands released following fertilization.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
