    Protein phosphatase 1 (PP1) is well known for their role in signal transduction and protein function. Together with its inhibitors 1 and 2, it regulates wide variety of cellular activities. We have amplified catalytic subunit of PP1 (PP1c) and its inhibitors 1 (I-1) and 2 (I-2) from dog cardiac mRNA by rt-PCR and cloned into bacterial expression vector pCRT7. Cloned genes were expressed in E. coli BL21 (DE3) pLysS by IPTG induction. Functional positive clones were identified by western blotting of bacterial lysate and polymerase chain reaction. Double transformed bacterial cells were also generated by transforming PP1c clone with either I-1 or I-2. Activity of PP1 was analyzed in whole bacterial lysate by measuring dephosphorylation of phos b. Activities of inhibitors were analyzed by their capability to inhibit PP1 from dephosphorylation of phos b. Our fi.. Read More»
