Disease relevance of PTAFR

 

Psychiatry related information on PTAFR

  • Taken together, these results demonstrate that PMS777 possesses dual activities for PAF receptor antagonism and AChE inhibition, suggesting that this compound may be a promising lead compound for further investigation related to the treatment for Alzheimer's disease [6].

Associations of PTAFR with chemical compounds

  • To investigate the specific role of dimerization in the internalization process of GPCRs, we generated a fusion protein of hPAFR and bacterial DNA gyrase B (GyrB), dimerized through the addition of coumermycin [25].
  • The presence of the PAF-R in these models resulted in an augmentation of apoptosis induced by chemotherapeutic agents etoposide and mitomycin C but not by tumor necrosis factor-related apoptosis-inducing ligand or by C(2) ceramide [20].
  • We show that, POVPC binds to cultured human macrophages via PAF-R and transduces the signals leading to the intracellular Ca(2+) fluxes and modifies the transcription levels of numerous pro-inflammatory and pro-atherogenic genes [24].
  • Sodium decreased specific (3)H-PAF and antagonist (3)H-WEB2086 binding to the PAF receptor, but the aspartate 63 residue was not involved in this regulation, contrary to cognate aspartate residues in other GPCRs [26].
  • Localization, quantification, and activation of platelet-activating factor receptor in human endometrium during the menstrual cycle: PAF stimulates NO, VEGF, and FAKpp125 [27].
