Mitofusin-2 Down-Regulation Predicts Progression of Non-Muscle Invasive Bladder Cancer

open access: yesDiagnostics, 2021
Identification of markers predicting disease outcome is a major clinical issue for non-muscle invasive bladder cancer (NMIBC). The present study aimed to determine the role of the mitochondrial proteins Mitofusin-2 (Mfn2) and caseinolytic protease P ...

Control of substrate gating and translocation into ClpP by channel residues and ClpX binding [PDF]

open access: yes, 2010
ClpP is a self-compartmentalized protease, which has very limited degradation activity unless it associates with ClpX to form ClpXP or with ClpA to form ClpAP.

A processive rotary mechanism couples substrate unfolding and proteolysis in the ClpXP degradation machinery

open access: yeseLife, 2020
The ClpXP degradation machine consists of a hexameric AAA+ unfoldase (ClpX) and a pair of heptameric serine protease rings (ClpP) that unfold, translocate, and subsequently degrade client proteins.

Crystal structure of Mycobacterium tuberculosis ClpP1P2 suggests a model for peptidase activation by AAA+ partner binding and substrate delivery [PDF]

open access: yes, 2014
Caseinolytic peptidase P (ClpP), a double-ring peptidase with 14 subunits, collaborates with ATPases associated with diverse activities (AAA+) partners to execute ATP-dependent protein degradation.

Mitochondrial Quality Control in Age-Related Pulmonary Fibrosis. [PDF]

open access: yes, 2020
Idiopathic pulmonary fibrosis (IPF) is age-related interstitial lung disease of unknown etiology. About 100,000 people in the U.S have IPF, with a 3-year median life expectancy post-diagnosis.

Protein purification to analyze AAA+ proteolytic machine in vitro [PDF]

open access: yes, 2011
The ATP-dependent ClpXP protease of Escherichia coli consists of two subunits, the ClpP subunit, which has the proteolytic activity and the AAA+ motor ClpX, which mechanically unfolds and translocates substrates for ClpP degradation.

Highly Dynamic Interactions Maintain Kinetic Stability of the ClpXP Protease During the ATP-Fueled Mechanical Cycle [PDF]

open access: yes, 2016
The ClpXP protease assembles in a reaction in which an ATP-bound ring hexamer of ClpX binds to one or both heptameric rings of the ClpP peptidase. Contacts between ClpX IGF-loops and clefts on a ClpP ring stabilize the complex.

ClpP: A distinctive family of cylindrical energy‐dependent serine proteases

open access: yesFEBS Letters, 2007
Processes maintaining protein homeostasis in the cell are governed by the activities of molecular chaperones that mainly assist in the folding of polypeptide chains and by a large class of proteases that regulate protein levels through degradation. ClpP proteases define a distinctive family of cylindrical, energy‐dependent serine proteases that are ...

ClpA mediates directional translocation of substrate proteins into the ClpP protease [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
The intracellular degradation of many proteins is mediated in an ATP-dependent manner by large assemblies comprising a chaperone ring complex associated coaxially with a proteolytic cylinder, e.g., ClpAP, ClpXP, and HslUV in prokaryotes, and the 26S proteasome in eukaryotes.

Mitochondrial ClpP serine protease-biological function and emerging target for cancer therapy [PDF]

open access: yesCell Death & Disease, 2020
AbstractMitochondrial ClpP is a serine protease located in the mitochondrial matrix. This protease participates in mitochondrial protein quality control by degrading misfolded or damaged proteins, thus maintaining normal metabolic function. Mitochondrial ClpP is a stable heptamer ring with peptidase activity that forms a multimeric complex with the ATP-
