title: Characterization and partial purification of a membrane protein from rabbit skeletal muscle which inhibits the cAMP-dependent protein kinase.
abstract: Rabbit skeletal muscle membranes contain a protein which inhibits the cAMP-dependent protein kinase. The activity of the partially purified membrane protein is characterized by an IC-50 of 10 to 30 nM with respect to the inhibition of the activity of the catalytic subunit of the cAMP-dependent protein kinase and is sensitive to treatment with heat, acid, alkali and trypsin. The active fractions contain proteins ranging from 40 to 120 kDa, analysed by SDS-gel electrophoresis.
