Here, we developed a compact drug-induced splicing system that maintains low background using a human ubiquitin C (hUBC) promoter and optimized drug (LMI070) binding sequences based on the Xon switch system. To ensure precise subcellular localization of the protein of interest (POI), we inserted a 2A self-cleaving peptide between the extra N-terminal peptide and POI. This streamlined and optimized switch system, named miniXon2G, effectively regulated POIs in different subcellular localizations both in vitro and in vivo. Furthermore, miniXon2G could be integrated into endogenous gene loci, resulting in precise, reversible regulation of target genes by both endogenous regulators and drugs.
