Complete Primary Structure of Protein Phosphatase Inhibitor‐1 from Rabbit Skeletal Muscle
Abstract
The complete primary structure of protein phosphatase inhibitor‐1 has been determined. The protein consists of a single polypeptide chain of 165 residues, molecular weight 18640. The threonine residue that must be phosphorylated for activation is at position 35 and the active cyanogen bromide peptide, CB‐1, comprises residues 2–66. The N‐terminal methionine is acetylated and 40% of the inhibitor‐1 molecules lack the C‐terminal dipeptide Ala‐Val. Serine‐67 is substantially phosphorylated in vivo, but this phosphoserine residue does not appear to influence the activity of inhibitor‐1.

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.
