TLDR
Analysis of the proteins present in different subcellular membrane fractions show that the novel 45 kDa polypeptide is an integral membrane constituent present both in neonatal and adult skeletal-muscle sarcoplasmic reticulum and can be phosphorylated in vitro by the catalytic subunit of protein kinase A.
