Multiple phosphorylation sites in mammalian neurofilament polypeptides.
Open accessAbstract
The 68,000, 145,000, and 200,000 dalton subunits of neurofilaments from rat spinal cord and brain stem were shown by chemical phosphate analysis to contain about 3, 9, and 22 mol of phosphate/mol of polypeptide, respectively. All three subunits contained phosphoserine while the 145,000 dalton polypeptide also contained phosphothreonine. The high phosphate content of the 200,000 dalton polypeptide was reflected by the extensive shifts both in its isoelectric point and apparent molecular weight after treatment of neurofilaments with alkaline phosphatase.

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.
