abstract：:We have shown that protein kinase A phosphorylation of t-SNAREs inhibits SNARE assembly and suppresses endo- and exocytosis in yeast. Herein, we show that protein kinase A phosphorylation of the Sso exocytic t-SNAREs promotes the binding of Vsm1, a potential SNARE regulator identified previously in our laboratory. Pho...
