Abstract

We have compared the amino acid and carbohydrate compositions, partial amino acid sequences, immunological crossreactivity, and physical properties of secretory protein I of the parathyroid gland and chromogranin A of adrenal gland. This comparison indicates that these proteins are similar molecules. Because secretory protein I is present in secretory granules containing parathormone and is cosecreted with the hormone, and because chromogranin A is contained within chromaffin granules and, likewise, is secreted with the catecholamines, the present observations raise the possibility that this class of protein plays a general role in hormone secretion or storage mechanisms.

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.
