PhoCl Display mRuby

PhoCl Display mRuby Backbone is modified from the RELEASE system. It contains a mRuby as the protein of interest, PhoCl2c, a tri-transmembrane domain and an ER retention motif. The furin cut site, HCV cut site, and GFP were removed. PhoCl Display will display a protein of interest on the cell membrane in response to ultraviolet light stimulation.

Usage and Biology

Our project builds on the protein circuit RELEASE (Vlahos et al.) by introducing light-inducible proteins or photoswitches. Photocleavable protein (PhoCl) is a recently developed optogenetic technology that self-cleaves when stimulated by 405 nm ultraviolet light. PhoCl was engineered from a green-to-red photoconvertible fluorescent protein. When stimulated with ultraviolet light, the protein undergoes a β-elimination reaction, producing a small peptide fragment and a large barrel fragment that will spontaneously dissociate (Zhang et al.).

Mechanism: Upon light-activation Phocl breaks, removing the ER retention motif and allowing the protein to continue along the secretion pathway. The absence of the furin cut site means the POI remains bound to the membrane of the vesicle. At the plasma membrane the POI will be displayed.
