Webb6 dec. 2024 · We designed and implemented a recombinant protein with a SpyCatcher domain connected to a cell-adhesive RGDS peptide domain by a light-cleavable domain known as PhoCl. This protein was shown to bind to SpyTag-functionalized PEG-matrices via SpyTag-SpyCatcher isopeptide bonding to present RGDS adhesive ligands to cells. Webb16 mars 2024 · Researchers at the University of Alberta have developed a new method of controlling biology at the cellular level using light. The tool—called a photocleavable protein—breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways.
WebbPhoCl may enable a generic approach for optogenetic activa- tion of enzymes if it is used as a photocleavable linker between an enzyme and its proteinaceous inhibitor. Webb9 dec. 2024 · Here, we report the X-ray crystal structures of the PhoCl1 green state, red state, and cleaved empty barrel. Molecular dynamics (MD) simulations were performed to provide insight into the precise dissociation mechanism. Using structure-guided engineering and directed evolution, we have developed PhoCl2c with higher contrast …
WebbSeveral different screening systems based on bimolecular fluorescence complementation and FRET were developed to screen directly for the photoinduced dissociation of a photocleavable protein (PhoCl) developed in our lab. A second photocleavable protein called SplitOr was created from PSmOrange2. Webb31 maj 2024 · PhoCl variants: PhoCl2c with higher dissociation contrast ratio, and PhoCl2f with faster dissociation rate. Optogenetic control of protein localization by PhoCl2 variants
WebbThe improved performance of PhoCl2c is also made apparent by the fact that this variant induced a greater degree of capase-3 activation compared to PhoCl1 (Fig. 5F). Cell …
