Disease relevance of YWHAQ

 

High impact information on YWHAQ

 

Biological context of YWHAQ

 

Anatomical context of YWHAQ

  • Identification of HS1 protein as a major substrate of protein-tyrosine kinase(s) upon B-cell antigen receptor-mediated signaling [9].
  • Expression of the human HS1 protein from an expression vector introduced into one of the variant cell lines restored the sensitivity of the cells to apoptosis induced by surface IgM crosslinking [5].
  • Additionally, no tyrosine phosphorylation of HS1 was induced by mitogenic pairs of anti-CD2 mAbs capable of activating the transcription factor NFAT (nuclear factor of activated T cells) [8].
  • All together these results indicate that HS1 Tyr phosphorylation catalyzed by Syk and Lyn plays a crucial role in the translocation of the protein to the membrane and is involved in the cytoskeleton rearrangement triggered by thrombin in human platelets [10].
  • Immunofluorescence microscopic analysis shows that the agonist promotes HS1 migration to the plasma membrane and that the inhibition of Lyn-mediated secondary phosphorylation of HS1 abrogates the subcellular translocation of the protein [10].
 

Associations of YWHAQ with chemical compounds

  • 1C5 recognizes the region 119-130 corresponding to the GXXXG motif, the glycine zipper region, conserved in all mammals [11].
  • By means of specific inhibitors (PP2, SU6656, and piceatannol) and phosphopeptide-specific antibodies, as well as by coimmunoprecipitation and binding competition experiments, we show that Syk acts as the primary kinase that phosphorylates HS1 at Tyr397 and that Syk phosphorylation is required for HS1 interaction with the Lyn SH2 domain [10].
  • 1C5 can be used for the staining of routine formalin-fixed and paraffin-embedded tissue sections [3].
  • 1C5 also reacts with 95% ethanol-fixed malignant cells in cervical smears [3].
  • Related studies have shown that citrate removed calcium bound by PPG; N6-substituted adenines were bound by PPG while three polyphosphorylated dinucleosides, HS3, HS2, and HS1, were displaced from it [12].
