Complete amino acid sequence of human plasma beta 2-glycoprotein I.
Open accessAbstract
We have determined the complete amino acid sequence of beta 2-glycoprotein I (Mr, congruent to 50,000), a human plasma protein that is associated with lipids and binds to platelets but whose function is not yet known. The protein consists of 326 amino acids and has five attached glucosamine-containing oligosaccharides. The protein is rich in cysteine and proline, and the sequence is notable for the frequent occurrence of Cys-Pro linkages at regular intervals. Computerized analysis of the sequence reveals five consecutive homologous segments in which cysteine, proline, and tryptophan appear to be highly conserved. This suggests that beta 2-glycoprotein I may have evolved by repeated duplications of a gene coding for a 60-amino acid segment of protein.

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.
