PSMA3 is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of PSMA3 is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
The PSMA3 gene encodes the alpha subunit type 3 of the 20S proteasome. PSMA3 is a critical component of the outer alpha ring of the 20S proteasome and plays a role in substrate recognition and gate regulation. The proteasome is the proteolytic core of the ubiquitin-proteasome system, responsible for degrading ubiquitinated proteins.
PSMA3 is essential for the assembly and function of the 20S proteasome complex. It contributes to the degradation of oxidized proteins, misfolded proteins, and short-lived regulatory proteins. The proteasome is particularly important in neurons due to their post-mitotic nature and inability to dilute damaged proteins through cell division.
