PSMB1 is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of PSMB1 is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
The PSMB1 gene encodes the β1 subunit of the 20S proteasome, also known as proteasome subunit β type-1. PSMB1 is a catalytic subunit that contributes the caspase-like (peptidylglutamyl peptide hydrolyzing) activity to the proteasome.
The proteasome β-ring contains three catalytic subunits: PSMB1 (β1, caspase-like), PSMB2 (β2, trypsin-like), and PSMB5 (β5, chymotrypsin-like). PSMB1 cleaves after acidic residues and contributes to the overall proteolytic activity of the proteasome.
