phosphorylation of phospholamban ( plb ) , a membrane-bound 15 kda protein and troponin i ( tni ) was studied in isolated perfused rat hearts by using the back-phosphorylation technique with [ 32p ] atp catalysed by an excess of exogenous catalytic subunit of cyclic amp ( camp ) -dependent protein kinase , followed by protein separation .
