Primary structure of human pepsinogen gene.
Open accessAbstract
A recombinant clone, which covers the pepsinogen gene in a single insert, has been isolated by screening a library of human genomic DNA, using a swine pepsinogen cDNA as a probe. Sequence analysis of coding DNA segments of the clone revealed that the pepsinogen gene occupies approximately 9.4-kilobase pairs of the genomic DNA and is separated into nine exons by eight introns of various lengths. The predicted amino acid sequence of human pepsinogen consists of 373 residues and is 82% homologous with that of swine pepsinogen. In addition, the predicted sequence contained a single sequence of 15 amino acid residues at the NH2 terminus, showing that the protein is synthesized as prepepsinogen. The structure of the gene, in which two homologous sequences including the two active site aspartyl residues of pepsin are present in different coding segments, is in support of the view that the pepsinogen gene evolved by duplication of a shorter ancestral gene.

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.
