Multiple polyadenylation sites in a mouse α-amylase gene
Open accessAbstract
Two alpha-amylase mRNAs which differ in the length of their 3' non-translated region accumulate in the cytoplasm in both mouse liver and salivary gland tissues. The two species in each tissue are transcribed from the same gene (Amy-1A). The minor species is approximately 20-nucleotides preceding the poly(A) tract. Sequence analysis of genomic DNA shows that these extra 237 nucleotides are specified by sequences contiguous to those shared by the two mRNAs. These data demonstrate that transcription can proceed through the major polyadenylation site and that alternative polyadenylation sites are used in the Amy-1A gene. Sequences which trail the two polyadenylation sites exhibit extensive homology and might therefore be involved in polyadenylation or transcription termination.

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.
