Abstract

Microinjection of the pure inhibitor (1) of cAMP dependent protein kinases (1.5 muM) into Xenopus oocytes triggered 100% germinal vesicle break down (GVBD), faster than progesterone and slower than the maturation promoting factor (MPF). Cholera toxin does not block (I) induced maturation; however cycloheximide inhibits (I) but not MPF induced GVBD.
