The protein phosphatase inhibitor‐1 (PPI‐1) inhibits phosphatase type‐1 (PP1) only when phosphorylated by protein kinase A and could play a pivotal role in the phosphorylation/dephosphorylation balance. Rat cardiac PPI‐1 was cloned by reverse transcriptase‐polymerase chain reaction, expressed in Eschericia coli, evaluated in phosphatase assays, and used to generate an antiserum. An adenovirus was constructed encoding PPI‐1 and green fluorescent protein (GFP) under separate cytomegalovirus… Expand
