Three 1-(2-nitrophenyl)ethyl-caged phospho-amino acids have been synthesized for use in standard N(alpha)-fluorenylmethoxycarbonyl-based solid-phase peptide synthesis (SPPS). The most common naturally occurring phospho-amino acids, serine, threonine, and tyrosine, were prepared as protected caged building blocks by modification with a unique phosphitylating

Bioorthogonal reactions, especially the Cu(I)-catalysed azide-alkyne cycloaddition, have revolutionized our ability to label and manipulate biomolecules under living conditions. The cytotoxicity of Cu(I) ions, however, has hindered the application of this reaction in the internal space of living cells. By

Desmosomes are prominent adhesive junctions found in various epithelial tissues. The cytoplasmic domains of desmosomal cadherins interact with a host of desmosomal plaque proteins, including plakophilins, plakoglobin and desmoplakin, which, in turn, recruit the intermediate filament cytoskeleton to sites of
