Recombinant Human Ubiquitin carboxyl-terminal hydrolase 30 (USP30), Truncated

Uniprot Id

Q70CQ3

Target Species

Human

Target Name

USP30

Target Full Name

Ubiquitin carboxyl-terminal hydrolase 30

Target Function

Deubiquitinating enzyme tethered to the mitochondrial outer membrane that acts as a key inhibitor of mitophagy by counteracting the action of parkin (PRKN): hydrolyzes ubiquitin attached by parkin on target proteins, such as RHOT1/MIRO1 and TOMM20, thereby blocking parkin's ability to drive mitophagy. Preferentially cleaves 'Lys-6'- and 'Lys-11'-linked polyubiquitin chains, 2 types of linkage that participate in mitophagic signaling. Does not cleave efficiently polyubiquitin phosphorylated at 'Ser-65'. Acts as negative regulator of mitochondrial fusion by mediating deubiquitination of MFN1 and MFN2.

Target Subcellular Location

Mitochondrion outer membrane.

Target Protein Families

Peptidase C19 family

Target Tissue Specificity

Expressed in skeletal muscle, pancreas, liver and kidney.

Target Background

USP30, a member of the ubiquitin-specific protease family (see USP1, MIM 603478), is a novel mitochondrial deubiquitinating (DUB) enzyme (Nakamura and Hirose, 2008 [PubMed 18287522]).
