Abstract. Intracellular delivery of functional proteins is emerging as a powerful strategy to interrogate and control cellular pathways with high spatial a

Covalent inhibitors and chemical probes targeting ligandable cysteine residues have emerged as powerful tools for drug discovery and proteomics. In this study, we introduce vinyl phosphonamidates (VPA...

Rhodamine dyes conjugated to targeting ligands can yield exceptionally bright fluorescent probes for live-cell imaging. However, the limited permeability of such rhodamine derivatives restricts their ...

Compartmentalization by organelles and the dynamic control of protein localization within these compartmentalized spaces are key mechanisms for regulating biological processes in eukaryotic cells. Here, we present a bottom-up approach for constructing cell-sized liposomes (giant unilamellar vesicles, GUVs) encapsulating an artificial organelle with chemically controlled protein localization. In this system, proteins fused to Escherichia coli dihydrofolate reductase are rapidly recruited on demand from the inner solution to the interior of a DNA-droplet-based (“nucleus”-like) organelle within GUVs upon addition of a synthetic, DNA-binding trimethoprim derivative to the external solution. By coupling this system with a sequence-specific protease, we constructed a synthetic cell platform that enables chemically induced, multistep cascade reactions─including protein relocalization, organelle-specific enzymatic activity, and product release from the organelle─that culminate in the control of synthetic-cell phenotypes, such as pore formation in the GUV membrane. This work provides a versatile platform for the bottom-up creation of eukaryotic-like synthetic cells with sophisticated and programmable functions.
