Gene Overview
Function
UCHL5 encodes a ubiquitin C-terminal hydrolase that hydrolyzes ubiquitin monomers and chains. It is part of the [ubiquitin-proteasome system](/mechanisms/ubiquitin-proteasome-system) (UPS) and plays a role in protein degradation and recycling.
Key Functions
Ubiquitin Processing: Generates free ubiquitin from precursors and polyubiquitin chains
Proteasome Function: Associated with the proteasome regulatory particle
Protein Quality Control: Clears misfolded and damaged proteins
DNA Repair: Involved in DNA damage response pathways
Disease Associations
Parkinson's Disease
UCHL5 is involved in PD pathogenesis through:
Regulation of alpha-synuclein degradation
Mitochondrial protein quality control
Ubiquitin pathway dysfunction in PD brains
Alzheimer's Disease
UPS dysfunction is a hallmark of AD
UCHL5 may affect [tau](/proteins/tau) degradation
Protein aggregate accumulation in AD brains
Cancer
Altered UCHL5 expression in various cancers
May affect tumor suppressor protein degradation
Expression
UCHL5 is expressed in most tissues:
Highest expression in brain and testis
Moderate expression in other tissues
Expressed in [neurons](/entities/neurons) and glial cells
In the brain:
Cerebral [cortex](/brain-regions/cortex)
[Hippocampus](/brain-regions/hippocampus)
Substantia nigra
[Cerebellum](/brain-regions/cerebellum)
Ubiquitin-Proteasome System
The UPS is the primary system for protein degradation in eukaryotic cells:
Ubiquitination: E1, E2, E3 enzymes attach ubiquitin to proteins
Proteasomal Recognition: Polyubiquitinated proteins are recognized
Degradation: Proteins are unfolded and degraded into peptides
Recycling: Ubiquitin is recycled
