• Ubiquitin-Specific Peptidase 30 also known as Ubiquitin-Specific Protease 30 (USP30).
• the ubiquitination system is a highly-regulated process which affects a wide variety of cellular activities and physiological processes. Dysregulation of this system is commonly associated with several human diseases, including cancer, neurodegenerative disorders, muscle dystrophies, and cardiomyophaties, amongst others (Popovic, et al., Nature Medicine 2014, 20, 1242-1253). Ubiquitination is a reversible process, facilitated by a group of proteins known as deubiquitinating enzymes (DUBs), which deconjugate ubiquitin (Ub) from the substrate. DUBs are encoded by approximately 100 human genes and are divided into six families, with the largest family being the ubiquitin-specific proteases (USPs) with more than 50 members.
• DUBs deubiquitin-specific proteases
• Mitochondria serve many functions to maintain cell health in mammals, including generating ATP. As mitochondria age they become damaged, losing their metabolic functionality and begin releasing pro-apoptotic proteins. Mitochondria self-regulate their quality via the mechanism of mitophagy, which is the selective removal of damaged mitochondria from the cell. In studies to determine what influences how mitochondria perform mitophagy, ubiquitination of mitochondrial proteins is believed to contribute to mitochondrial dynamics in mammalian cells, possibly by“flagging” those proteins for inactivation. USP30 is a
• USP30 is a mitochondrial DUB that opposes the ligase activity of Parkin and is a negative regulator of mitophagy. USP30 inhibition is expected to promote mitophagy and restore mitochondrial health.

• Parkin E3 ubiquitin ligase
• PINK1 kinase
• MIM mitochondrial inner membrane
• PINK1 is processed by several proteases, such as presenilin associated rhomboid-like protease (PARL), to yield a truncated version of PINK1 which is subsequently degraded by the proteasome (Meissner et ak, Autophagy. 2015, 11(9), 1484-1498).
• PARL presenilin associated rhomboid-like protease
• PINK1 Upon mitochondrial depolarization or dysfunction, PINK1 accumulates in the mitochondrial outer membrane (MOM), recruiting and activating Parkin via PINK 1 -dependent phosphorylation of both ubiquitin and Parkin. Consequently, activated Parkin ubiquitinates MOM proteins like TOMM20 to trigger mitophagy (Pickrell et ak, Neuron.
• MOM mitochondrial outer membrane
• USP30 is embedded in the MOM with its catalytic DUB domain oriented towards the cytosol and has been shown to antagonize Parkin-mediated ubiquitination of common substrates, consequently opposing Parkin-mediated mitophagy. Genetic silencing of USP30 results in increased ubiquitination of several Parkin substrates followed by increased mitophagy. In model organisms, USP30 depletion is able to rescue mitophagy defects caused by pathogenic Parkin mutations, as well as restore mitochondria morphology and function, and dopamine levels.
