Abstract

We present the complete sequence of an mRNA which is induced by estrogen in the human breast cancer cell line MCF-7 [pS2 mRNA, Masiakowski et al., Nucleic Acids Res. 10, 7895-7903 (1982)]. Primer extension and cloning of double-stranded cDNA (ds-cDNA) into a vector designed to make full-length cDNA were used to determine the sequence of the fifteen 5'-terminal nucleotides which were not present in the original pS2 ds-cDNA clone. The mRNA sequence has a major open reading frame encoding 84 amino-acids, flanked by a 40 nucleotide 5'-untranslated region and a 198 nucleotide 3'-untranslated region preceding the polyA tail. The 3'-untranslated region contains a polyadenylation signal, AUUAAA, 14 nucleotides upstream from the polyA tail. The derived protein sequence contains a putative signal peptide region suggesting that the protein may be secreted. The nucleotide and derived amino-acid sequences were compared to previously determined sequences, particularly to those of hormone-regulated proteins and growth factors, and no obvious similarities were observed.

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.
