Disease relevance of CRK


High impact information on CRK

  • These results suggest that both SH2 and SH3 of the CRK protein mediate specific protein-protein binding and that the resulting multimolecular complex generates a signal for neurite differentiation through activation of p21ras [1].
  • Furthermore, cell death induced by 280 nm UV irradiation were augmented by Btk depletion or a specific inhibitor for P38, and partially blocked in Lyn-deficient cells, suggesting that the Lyn-Btk-P38 pathway promotes cell survival while other Lyn pathways stimulate cell death [2].
  • Tyrosine phosphorylation of Lyn was induced by 280 nm UV light, and pretreatment of cells with orthovanadate, an inhibitor of protein tyrosine phosphatase (PTP), enhanced both Lyn phosphorylation and P38 activation [2].
  • This P38 kinase is, therefore, distinct from the hemin-regulated translational inhibitor of protein synthesis in rabbit reticulocytes and from the interferon-induced protein kinase identified In several systems [3].
