Uninfected vertebrate cells contain a protein that is closely related to the product of the avian sarcoma virus transforming gene (src).
Open accessAbstract
Neoplastic transformation of cell by avian sarcoma virus is mediated by a single viral gene (src), which encodes a phosphoprotein (pp60src) with the enzymatic activity of a protein kinase. The DNAs of vertebrate species contain a highly conserved homologue of src that is also represented in the polysomal RNA of uninfected cells and, hence, may specify a normal cellular protein. We have used antisera directed against pp60src to isolate a closely related phosphoprotein (denoted vertebrate pp60) from uninfected chicken, quail, rat, and human cells. Our data indicate that vertebrate pp60 is a homologue of pp60src, highly conserved both antigenically and chemically. Moreover, the cellular protein may possess protein kinase activity similar to that associated with pp60src. We conclude that the product of src is a slightly modified analogue of a normal cellular protein.

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.
