Function[SAV_STRAV] The biological function of streptavidin is not known. Forms a strong non-covalent specific complex with biotin (one molecule of biotin per subunit of streptavidin). Publication Abstract from PubMedChemical inducers that can control target-protein localization in living cells are powerful tools to investigate dynamic biological systems. We recently reported the retention using selective hook or "RUSH" system for reversible localization change of proteins of interest by addition/washout of small-molecule artificial ligands of streptavidin (ALiS). However, the utility of previously developed ALiS was restricted by limited solubility in water. Here, we overcame this problem by X-ray crystal structure-guided design of a more soluble ALiS derivative (ALiS-3), which retains sufficient streptavidin-binding affinity for use in the RUSH system. The ALiS-3-streptavidin interaction was characterized in detail. ALiS-3 is a convenient and effective tool for dynamic control of alpha-mannosidase II localization between ER and Golgi in living cells.
