PSMA5 is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of PSMA5 is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
The PSMA5 gene encodes the alpha subunit type 5 of the 20S proteasome. PSMA5 is a core component of the 20S proteasome core particle, forming part of the outer alpha ring that controls substrate entry. The proteasome is the central enzyme of the ubiquitin-proteasome system.
PSMA5 plays a structural role in maintaining proteasome assembly and function. The proteasome degrades ubiquitinated proteins, oxidized proteins, and misfolded proteins. In neurons, the proteasome is crucial for maintaining proteostasis given the post-mitotic nature of neurons.
