  • 7 The JAKs also trigger the activation and tyrosine phosphorylation of STAT5, causing parallel dimerization, nuclear translocation and tetramerization of STAT5. (nature.com)
  • Survival factors can suppress apoptosis in a transcription-independent manner by activating AKT1 which then phosphorylates and inactivates components of the apoptotic machinery. (senescence.info)
  • Nevertheless, ATP and Mn2+ and matching Akt1 amino acidity residues are indicated for clearness. (pkc-inhibitor.com)
  • Protein phosphatases act as negative regulators of AKT proteins by dephosphorylating AKT or PIP3. (senescence.info)
  • Phosphorylation at Tyr-568 is required for interaction with PTPN11/SHP-2, CRK (isoform Crk-II) and members of the SRC tyrosine-protein kinase family. (arigobio.com)
  • Phosphorylated SFKs displayed a punctate appearance at the neutrophil leading edge and the autophosphorylation depended on wounding (Fig. 1b c Supplementary Fig. 2a b). (cancerhugs.com)
  • 15 The dynamic addition and removal of O-GlcNAc has been described for multiple cytoplasmic and nuclear proteins and it affects the function of various signaling molecules and transcription factors. (nature.com)
  • Residues conserved across the rhoGAP family are largely confined to one face of this bundle, which may be an interaction site for target G proteins. (embl-heidelberg.de)
  • Upon cytokine stimulation, STAT5 tyrosine phosphorylation (pYSTAT5) is transient, while in diverse neoplastic cells persistent overexpression and enhanced pYSTAT5 are frequently found. (nature.com)
