Abstract

A carbohydrate-binding protein assayed by its ability to agglutinate formalinized sheep erythrocytes is synthesized between 3 and 9 hr after Dictyostelium discoideum cells are deprived of food, as the cells become cohesive. Agglutination of erythrocytes by this protein was inhibited by N -acetyl-D-galactosamine, D-galactose, and L-fucose, but other monosaccharides had little or no effect. The protein bound completely to Sepharose 4B, and was isolated in highly purified form by elution with D-galactose. It appears to be present on the surface of cohesive but not vegetative slime-mold cells. The possibility that this protein may mediate intercellular adhesion in Dictyostelium is considered.

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.
