Bioactivity | TSPO ligand-1 is the ligand of AUTAC4 (HY-134640) that can be used in the synthesis of PROTACs. TSPO ligand-1 is a mitochondrial outer membrane transmembrane structural domain protein can bind to AUTAC4 and regulate mitochondrial autophagy to promote targeted mitochondrial renewal. TSPO ligand-1 is also involved in the transport of cholesterol from the outer to inner mitochondrial membrane and serves as a sensitive biomarker of brain injury and neurodegeneration[1][2]. |
Invitro | TSPO ligand-1 gene is induced to increase expression in the context of selective activation of neurons in male C57Bl6/N mice. Moreover, neuronal activation under physiological and psychopharmacological conditions also results in increased TSPO levels in adult mice[2].TSPO ligand-1 can serve as the sole marker of glial cell activity in Alzheimer’s disease thus tracking the formation of different neural cells[3].TSPO ligand-1 can regulate mitochondrial fatty acid oxidation (FAO) and thus effects mitochondrial energy homeostasis in MA-10 Leydig cell line[4]. |
