Reversible inhibition of calcineurin by the polyphenolic aldehyde gossypol.
The reversible inhibition of calcineurin (CaN), which is the only Ca(2+)/calmodulin-dependent protein Ser/Thr phosphatase, is thought to be a key functional event for most cyclosporin A (CsA)- and tacrolimus (FK506)-mediated biological effects. In addition to CaN inhibition, however, CsA and FK506 have multiple biochemical effects because of their action in a gain-of-function model that require...
متن کاملResponses of multiple generations of Spodoptera littoralis feeding on gossypol
One of our objectives in this investigation is to determine responses of S. littoralis through different developmental stages and generations to secondary metabolic compound presumably gossypol. Gossypol did not significantly show antifeedant except with high concentration (1.7% gossypol in the diet) that gave 10.6, 21.9, and 46.8% for three generations, respectively. Significantly longer larva...

متن کاملTargeted proteolysis sustains calcineurin activation.
BACKGROUND Calcineurin (CnA) is important in the regulation of myocardial hypertrophy. We demonstrated that targeted proteolysis of the CnA autoinhibitory domain under pathological myocardial workload leads to increased CnA activity in human myocardium. Here, we investigated the proteolytic mechanism leading to activation of CnA. METHODS AND RESULTS In patients with diseased myocardium, we fo...
متن کاملSubunit and Plectin at Multiple Molecular Sites
Recent studies with patients suffering from epidermolysis bullosa simplex associated with muscular dystrophy and the targeted gene disruption in mice suggested that plectin, a versatile cytoskeletal linker and intermediate filament-binding protein, may play an essential role in hemidesmosome integrity and stabilization. To define plectin’s interactions with hemidesmosomal proteins on the molecu...
