Tyrosine Kinase-Stimulated Guanine Nucleotide Exchange Activity of Vav in T Cell Activation

Gulbins, Erich, Coggeshall, K. Mark, Baier, Gottfried, Katzav, Shulamit, Burn, Paul, Altman, Amnon·1993·Science

Abstract

The hematopoietically expressed product of the vav proto-oncogene, Vav, shares homology with guanine nucleotide releasing factors (GRFs) [also called guanosine diphosphate-dissociation stimulators (GDSs)] that activate Ras-related small guanosine triphosphate (GTP)-binding proteins. Human T cell lysates or Vav immunoprecipitates possessed GRF activity that increased after T cell antigen receptor (TCR)-CD3 triggering; an in vitro-translated Vav fragment that contained the putative GRF domain was also active. Vav-associated GRF stimulation after TCR-CD3 ligation paralleled its tyrosine phosphorylation; both were blocked by a protein tyrosine kinase (PTK) inhibitor. Vav also was a substrate for the p56 lck PTK. Thus, Vav is a PTK-regulated GRF that may be important in TCR-CD3-initiated signal transduction through the activation of Ras.

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.
