Photocaged serine

WebJan 30, 2014 · Photocaged lysine, tyrosine, and serine have been site specifically incorporated in place of key residues, allowing photocontrol of nuclear localization sequences, kinases, and other enzymes, and photocontrol of the sites of post-translational modification. 2,4,8−11 These approaches have revealed the kinetics, and … In another example, Chen et al. synthesized two-photon-activatable chemokine CCL5 using photocaged serine through efficient one-pot total chemical synthesis. The chemical groups at serine residues successfully caged the hCCL5 activity, which allowed a spatiotemporally controlled photoactivation of the chemokine activity [22].
