Manually controlling siRNA activity is an essentially important way to spatiotemporally investigate gene expression and function. Owing to ease of operation and precise manipulation, light can be used for controlled regulation of siRNA-induced gene silencing. Here, we developed a series of caged siRNAs with folic acid modification at the 5′ terminus of the antisense strand of the siRNA through a photolabile linker. The attachment of the folic acid moiety temporarily masked the corresponding siRNA activity. Upon illumination, these caged siRNAs were activated, and their gene silencing activities were restored. Based on this strategy, we successfully photomodulated gene expression of both an exogenous gene (for green fluorescent protein, GFP) and an endogenous gene (for mototic kinesin-5, Eg5) in cells.

We have used a photocaging strategy to develop novel phosphoramidites and expand the repertoire of protecting groups for modification of oligonucleotides by solid-phase synthesis. We synthesised five photolabile phosphoramidites and four new photolabile c

Prenylation is an essential post-translational modification in all eukaryotes. Here we describe the synthesis of a 340-member library of peptides containing free C-termini on cellulose membranes. The resulting library was then used to probe the specificit
