The 26S proteasome is a multicatalytic proteinase complex consisting of a 20S core and a 19S regulator. The 20S core has 4 rings made of 28 subunits, while the 19S regulator includes a base with ATPase subunits and a lid with non-ATPase subunits. Proteasomes, located throughout eukaryotic cells, cleave peptides in an ATP/ubiquitin-dependent process. The immunoproteasome processes class I MHC peptides. This gene encodes an ATPase subunit, part of the triple-A family of ATPases with chaperone-like activity. Beyond proteasome function, it may also participate in transcriptional regulation, interacting with thyroid hormone and retinoid X receptors. Two isoforms of this gene are produced by alternative splicing.
