the microtubule-associated processes that were moderately inhibited by phenyl saligenin cyclic phosphate in sensitive species were : in vitro [ 3h ] camp binding to protein kinase , in vitro assembly when tubulin rings were absent , and camp-dependent phosphorylation of microtubule-associated proteins ( maps ) both in vitro and on intracerebral administration of 32pi .
