UCHL1 (Ubiquitin C-terminal Hydrolase L1), also known as PGP 9.5 (Protein Gene Product 9.5), is a neuron-specific deubiquitinating enzyme. It is one of the most abundant proteins in the brain, constituting 1-5% of total soluble protein in neurons. UCHL1 is essential for maintaining the ubiquitin pool and proper synaptic function.
UCHL1 has a characteristic ubiquitin hydrolase fold:
The protein forms a compact, single-domain structure with the catalytic center accessible to substrates.
UCHL1 is the major neuronal deubiquitinating enzyme:
In neurons, UCHL1 is essential for:
| Approach | Description | Status |
|---|---|---|
| UCHL1 Activators | Enhance deubiquitinating activity | Research |
| Gene Therapy | Restore UCHL1 function | Preclinical |
| Proteostasis Enhancers | General UPS enhancement | Research |
UCHL1 research utilizes several animal models:
