Fig. 9.
Time course of equilibration of a Ca2+/calmodulin-dependent protein kinase II (CaMKII)-protein phosphatase 1 (PP1) system. Shown is the CaMKII autonomy versus time at eight different values of [Ca2+] (± SD, n = 2). White and black bars represent experiments initiated with dephosphorylated and phosphorylated CaMKII, respectively.
