Abstract

The single-chain form of human urokinase plasminogen activator (uPA) is the major form of the enzyme found in cells, tissues, and extracellular fluids. The protein, called pro-uPA, has high (Kd = 0.5 nM) affinity for the specific uPA receptor of U937 human monocyte-like cells. Its conversion to two-chain uPA by plasmin does not appreciably change the binding parameters. In addition, conversion of pro-uPA to uPA occurs with receptor-bound pro-uPA and does not lead to dissociation from the membrane. These data show that secreted pro-uPA can find its way to the specific surface receptor without previous conversion to the two-chain form and that, once bound, can be activated by plasmin.

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.
