Abstract:
Phospholamban was purified by two different preparation protocols. The products of both preparations are immunochemical similar. They differ, however, with regard to their phosphorylation by the catalytic subunit of cAMP-dependent protein kinase. It is suggested that the lipid environment plays a crucial role in the exposition of the phosphorylation sites of phospholamban.

Phosphorylation
The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...

Protein Kinases and Phosphatases
Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
