It has a molecular weight of approximately 29 kDa. PSME3 is mainly found in the nucleus and shows strong expression in various tissues including liver kidney and heart. The protein operates by binding to the 20S proteasome core and enhances the specificity of proteolytic activity.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPSME3 regulates cell cycle progression and apoptosis. It is part of a larger multiprotein complex with the 20S proteasome core forming an important component in protein homeostasis. PSME3’s interaction with the proteasome core significantly reduces the accumulation of certain regulatory proteins by promoting their degradation. This function affects several cellular processes such as cell proliferation and DNA repair aiding the maintenance of cellular function and integrity.\u003cbr\u003e\nPathways\u003cbr\u003e\nPSME3 plays a critical role in mediating the ubiquitin-proteasome pathway and the MDM2-p53 pathway. In the ubiquitin-proteasome pathway it assists in the controlled turnover of intracellular proteins which is pivotal for maintaining cellular protein quality. In the MDM2-p53 pathway it affects the stability of the p53 protein by enhancing the degradation of both MDM2 and p53 therefore modulating apoptosis and growth arrest in cells under stress or DNA damage conditions.\u003cbr\u003e\nDisruptions in PSME3 function correlate with cancer and neurodegenerative disorders. Overexpression of PSME3 is often linked to oncogenesis due to its role in controlling the degradation of tumor suppressor proteins like p53. This protein is also implicated in Parkinson’s disease where its interaction with pathogenic proteins suggests it might contribute to the accumulation of misfolded proteins. PSME3 along with its pathways and related proteins offers potential as a target for therapeutic intervention in these diseases.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848646611113,"sku":"ab157157","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab157157","provider":"Iright","version":"1.0","type":"link"}
