Specifically, we control the nuclear localization of the Mmd2-binding PMI peptide using the light-inducible export system LEXY. In the dark, the PMI-LEXY fusion is nuclear and binds to Mdm2, consenting to p53 to accumulate and transcribe the target …

WebJul 11, 2024 · It is often valuable to stably express optogenetic proteins under the control of an inducible promoter , to prevent compensation, and for more convenient tissue culture. … WebJul 8, 2024 · Multiple optogenetic devices have been developed to manipulate nuclear protein import and export, but molecular tools tailored for remote control over selective targeting or partitioning of cargo proteins into subnuclear compartments capable of phase separation are still limited.
WebJan 22, 2024 · The Di Ventura lab has developed an optogenetic tool for light-inducible protein import to the nucleus ( 56 ). They combined NLS with the second light-oxygen-voltage (LOV2) domain of Avena sativa phototropin 1 that sterically conceals the NLS from the nuclear import machinery in dark. WebDownloadable! Active nucleocytoplasmic transport is a key mechanism underlying protein regulation in eukaryotes. While nuclear protein import can be controlled in space and time with a portfolio of optogenetic tools, protein export has not been tackled so far. Here we present a light-inducible nuclear export system (LEXY) based on a single, genetically …
