Interactions between proteins and lipids find increasing interest as a mean of regulating cellular functions. Until recently their study in living cells were nearly impossible. Therefore, we developed photoactivatable radioactive lipids that allow discovery of the protein interaction partners. These lipids contain a diazirine ring that can be activated by UV-light to form covalent links to any interaction partner (Thiele et al. 2000).
After we originally described the method [I.] we and many others have successfully used the technology to demonstrate specific interaction between proteins and certain lipids . [II.-XI.]
