Function

The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a non-ATPase subunit of the 19S regulator. Two transcripts encoding different isoforms have been described. Pseudogenes have been identified on chromosomes 3 and 20.{{cite web | title = Entrez Gene: PSMD10 proteasome (prosome, macropain) 26S subunit, non-ATPase, 10| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5716}}

Clinical significance

The proteasome and its subunits are of clinical significance for at least two reasons: (1) a compromised complex assembly or a dysfunctional proteasome can be associated with the underlying pathophysiology of specific diseases, and (2) they can be exploited as drug targets for therapeutic interventions. More recently, more effort has been made to consider the proteasome for the development of novel diagnostic markers and strategies. An improved and comprehensive understanding of the pathophysiology of the proteasome should lead to clinical applications in the future.

The proteasomes form a pivotal component for the ubiquitin–proteasome system (UPS) {{cite journal | vauthors = Kleiger G, Mayor T | title = Perilous journey: a tour of the ubiquitin–proteasome system | journal = Trends in Cell Biology | volume = 24 | issue = 6 | pages = 352–9 | date = Jun 2014 | pmid = 24457024 | pmc = 4037451 | doi = 10.1016/j.tcb.2013.12.003 }} and corresponding cellular Protein Quality Control (PQC). Protein ubiquitination and subsequent proteolysis and degradation by the proteasome are important mechanisms in the regulation of the cell cycle, cell growth and differentiation, gene transcription, signal transduction and apoptosis.{{cite journal | vauthors = Goldberg AL, Stein R, Adams J | title = New insights into proteasome function: from archaebacteria to drug development | journal = Chemistry & Biology | volume = 2 | issue = 8 | pages = 503–8 | date = Aug 1995 | pmid = 9383453 | doi=10.1016/1074-5521(95)90182-5| doi-access = free }} Subsequently, a compromised proteasome complex assembly and function lead to reduced proteolytic activities and the accumulation of damaged or misfolded protein species.

UPS proteolysis plays a major role in responses of cancer cells to stimulatory signals that are critical for the development of cancer. Accordingly, gene expression by degradation of transcription factors, such as p53, c-jun, c-Fos, NF-κB, c-Myc, HIF-1α, MATα2, STAT3, sterol-regulated element-binding proteins and androgen receptors are all controlled by the UPS and thus involved in the development of various malignancies.{{cite journal | vauthors = Adams J | title = Potential for proteasome inhibition in the treatment of cancer | journal = Drug Discovery Today | volume = 8 | issue = 7 | pages = 307–15 | date = Apr 2003 | pmid = 12654543 | doi=10.1016/s1359-6446(03)02647-3}} Moreover, the UPS regulates the degradation of tumor suppressor gene products such as adenomatous polyposis coli (APC) in colorectal cancer, retinoblastoma (Rb). and von Hippel–Lindau tumor suppressor (VHL), as well as a number of proto-oncogenes (Raf, Myc, Myb, Rel, Src, Mos, ABL). The UPS is also involved in the regulation of inflammatory responses. This activity is usually attributed to the role of proteasomes in the activation of NF-κB which further regulates the expression of pro inflammatory cytokines such as TNF-α, IL-β, IL-8, adhesion molecules (ICAM-1, VCAM-1, P-selectin) and prostaglandins and nitric oxide (NO). Additionally, the UPS also plays a role in inflammatory responses as regulators of leukocyte proliferation, mainly through proteolysis of cyclines and the degradation of CDK inhibitors.{{cite journal | vauthors = Ben-Neriah Y | title = Regulatory functions of ubiquitination in the immune system | journal = Nature Immunology | volume = 3 | issue = 1 | pages = 20–6 | date = Jan 2002 | pmid = 11753406 | doi = 10.1038/ni0102-20 | s2cid = 26973319 }} Lastly, autoimmune disease patients with SLE, Sjögren syndrome and rheumatoid arthritis (RA) predominantly exhibit circulating proteasomes which can be applied as clinical biomarkers.{{cite journal | vauthors = Egerer K, Kuckelkorn U, Rudolph PE, Rückert JC, Dörner T, Burmester GR, Kloetzel PM, Feist E | title = Circulating proteasomes are markers of cell damage and immunologic activity in autoimmune diseases | journal = The Journal of Rheumatology | volume = 29 | issue = 10 | pages = 2045–52 | date = Oct 2002 | pmid = 12375310 }}
