Protein phosphorylation in isolated nuclei from etiolated Avena seedlings. Effects of red/far-red light and cholera toxin.

abstract：:We have investigated the effect of botulinum neurotoxin (BoNT) C1 light chain (LC) on insulin exocytosis from the clonal beta-cell line HIT-T15. In streptolysin-O permeabilized cells, the beta-cell impermeant BoNT C1 cleaved mainly syntaxin 1 and inhibited Ca2+ as well as GTPgammaS induced exocytosis. To study the eff...
