Abstract

A synthetic DNA based on the known amino acid sequence of the brain/gut peptide cholecystokinin (CCK) was synthesized. This DNA contained deoxyinosines at ambiguous codon positions and was used as a probe to isolate the CCK gene directly from a human genomic library. Nucleotide sequence analysis of the isolated gene revealed that human preprocholecystokinin consists of 115 amino acid residues, with 11 amino acids in common with the human gastrin precursor, another member of the gastrin-CCK family, and that the coding region is separated by a single, long intron. CCK appears to be encoded by a single-copy gene in the haploid human genome, as revealed by genomic Southern hybridization analysis, suggesting that the same gene is expressed both in gut and brain.

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.
