摘要：

Protein phosphatase activities were analyzed in vivo in Xenopus oocytes. The dephosphorylation of microinjected-beta-casein was inhibited when the tumor promoter okadaic acid was microinjected into oocytes. Inhibition was dose dependent and reversible; 50 % of activity was recovered 15-30 minutes after microinjection.
