Ubiquitin-specific protease 30 (USP30) is a deubiquitinating enzyme belonging to the ubiquitin-specific protease family, which regulates protein degradation by removing ubiquitin tags from substrates. Predominantly localized to the outer mitochondrial membrane, USP30 plays a critical role in mitochondrial quality control and dynamics. It counteracts Parkin-mediated mitophagy, a selective autophagy process that removes damaged mitochondria, by cleaving ubiquitin chains attached to mitochondrial proteins. This function positions USP30 as a key modulator of cellular responses to mitochondrial stress and metabolic homeostasis.
Structurally, USP30 contains a transmembrane domain anchoring it to mitochondria and a catalytic domain responsible for its deubiquitinase activity. Dysregulation of USP30 has been implicated in neurodegenerative diseases, particularly Parkinson’s disease, due to its interaction with the PINK1/Parkin pathway. Overexpression of USP30 inhibits mitophagy, contributing to the accumulation of dysfunctional mitochondria, while its depletion enhances mitochondrial clearance.
Recombinant human USP30 protein is widely used in biochemical and cell-based studies to investigate mitochondrial biology, ubiquitin signaling, and therapeutic targeting. Its applications span drug discovery for conditions linked to mitochondrial dysfunction, including neurodegeneration, cancer, and metabolic disorders. Researchers utilize recombinant USP30 to screen inhibitors or study enzyme-substrate interactions, aiming to develop therapies that modulate mitophagy and cellular quality control pathways.
