Abstract

Lysosomal labile Zn2+ levels have been unclear. By targeting a small-molecule fluorescent Zn2+ probe, ZnDA-3H, to lysosomes via VAMP7-Halo, the lysosomal labile Zn2+ concentration was determined to be 1.9 nM in HeLa cells. Furthermore, ZnDA-3H enabled direct visualization of the Zn2+ efflux from the lysosomes to cytosol upon TRPMLs activation.

期刊介绍: The Journal of Inorganic Biochemistry is an established international forum for research in all aspects of Biological Inorganic Chemistry. Original papers of a high scientific level are published in the form of Articles (full length papers), Short Communications, Focused Reviews and Bioinorganic Methods. Topics include: the chemistry, structure and function of metalloenzymes; the interaction of inorganic ions and molecules with proteins and nucleic acids; the synthesis and properties of coordination complexes of biological interest including both structural and functional model systems; the function of metal- containing systems in the regulation of gene expression; the role of metals in medicine; the application of spectroscopic methods to determine the structure of metallobiomolecules; the preparation and characterization of metal-based biomaterials; and related systems. The emphasis of the Journal is on the structure and mechanism of action of metallobiomolecules.
