Charged surface residues of FKBP12 participate in formation of the FKBP12-FK506-calcineurin complex.
The mechanism of FK506 immunosuppression has been proposed to proceed by formation of a tight-binding complex with the intracellular 12-kDa FK506-binding protein (FKBP12). The FK506-FKBP12 complex then acts as a specific high-affinity inhibitor of the intracellular protein phosphatase PP2B (calcineurin), interrupting downstream dephosphorylation events required for T-cell activation. Site-direc...
متن کاملCharacterization of the FKBP12-Encoding Genes in Aspergillus fumigatus
Invasive aspergillosis, largely caused by Aspergillus fumigatus, is responsible for a growing number of deaths among immunosuppressed patients. Immunosuppressants such as FK506 (tacrolimus) that target calcineurin have shown promise for antifungal drug development. FK506-binding proteins (FKBPs) form a complex with calcineurin in the presence of FK506 (FKBP12-FK506) and inhibit calcineurin acti...
متن کاملSilver nanoparticles, a potential alternative to conventional anti-fungal agents to fungal pathogens affecting crop plants
Metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible White button Mushroom (Agaricus bisporus). The physical properties of these particles, size and shapes have been determined using techniques like TEM, FTIR and XRD and were reported in our earlier report. But, what stands of paramount importance in the presen...

متن کاملSynergistic antifungal activities of bafilomycin A(1), fluconazole, and the pneumocandin MK-0991/caspofungin acetate (L-743,873) with calcineurin inhibitors FK506 and L-685,818 against Cryptococcus neoformans.
Cryptococcus neoformans is an opportunistic fungal pathogen that causes life-threatening infections of the central nervous system. Existing therapies include amphotericin B, fluconazole, and flucytosine, which are limited by toxic side effects and the emergence of drug resistance. We recently demonstrated that the protein phosphatase calcineurin is required for growth at 37 degrees C and virule...
