    A) Immunoblot of PRKAR1A phosphorylation sites S77 and S83 in STK25 +/+ and STK25 -/- cardiomyocyte protein lysates. B) Immunoblots of phosphorylation sites S77 and S83 of PRKAR1A in STK25 -/- cardiomyocytes transfected with empty vector (EV), wild type STK25 and kinase dead K49R/T174A (loaded in duplicate). C) Forskolin (10μM) stimulated STK25 +/+ and STK25 -/- cardiomyocytes immunoblotted for phosphorylation of PRKAR1A and RYR2. D) Immunoprecipitation of Flag-STK25 expressed in HEK293T cells and immunoblotted for PRKAR1A and GM130 (positive control binding partner). E) Co-immunoprecipitation of PRKAR1A-V5 with STK25 and PRKACA in HEK293T cells treated with forskolin (10μM). F) In vitro kinase assay of purified STK25 and PRKAR1A, immunoblotted for phosphorylation of S83 of PRKAR1A.
