A soybean cDNA encoding a chromatin-binding peptide inhibits mitosis of mammalian cells.

Galvez, Alfredo F., de Lumen, Benito O.·1999·Nature Biotechnology

Abstract

A soybean cDNA encoding the small subunit peptide of a cotyledon-specific 2S albumin (Gm2S-1) is thought to play a role in arresting mitosis during the DNA endoreduplication and cell expansion phase of seed development. The peptide (termed lunasin) contains the cell adhesion motif Arg-Gly-Asp (RGD) followed by eight aspartic acid residues at its C-terminal end. A chimeric gene encoding the lunasin peptide tagged with green fluorescent protein (GFP) arrested cell division, caused abnormal spindle fiber elongation, chromosomal fragmentation, and cell lysis when transiently transfected into murine embryo fibroblast, murine hepatoma, and human breast cancer cells. Deletion of the polyaspartyl end abolished the antimitotic effect. Subcellular localization of lunasin and immunobinding assay using synthetic peptides revealed the preferential adherence of lunasin to chromatin. Immunofluorescence showed that kinetochore proteins were displaced from the centromere in lunasin-transfected cells. These observations suggest that lunasin binds to the chromatin, leading to disruption of kinetochore formation and inhibition of mitosis.

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.
