The molecular weight of PSMB1 is approximately 26 kDa. PSMB1 expression occurs in various tissues suggesting its wide involvement in cellular processes. This subunit contributes to the proteolytic activity of the 20S core within the proteasome facilitating protein degradation which is essential for maintaining cellular homeostasis.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPSMB1 functions as part of the proteasome's 20S core particle. This complex is responsible for most of the protein degradation in cells particularly targeting misfolded or damaged proteins for ubiquitin-mediated proteolysis. The breakdown of proteins is essential for cellular processes like cell cycle regulation and response to oxidative stress. PSMB1 also helps in the processing of antigens for presentation on MHC class I molecules influencing immune surveillance.\u003cbr\u003e\nPathways\u003cbr\u003e\nPSMB1 involvement is significant in the ubiquitin-proteasome pathway a central pathway in protein catabolism. This pathway enables the cell to control protein levels and quality interacting closely with proteins such as ubiquitin and other proteasome subunits like PSMC2 or PSMA3. Additionally PSMB1 contributes to the regulation of the NF-kB signaling pathway which is important for immune and inflammatory responses by degrading inhibitors that keep NF-kB inactive.\u003cbr\u003e\nPSMB1 has connections with cancer and neurodegenerative diseases like Alzheimer’s. Its role in protein degradation impacts the accumulation of dysfunctional proteins that characterize these diseases. Overexpression or mutation of PSMB1 may affect its interaction with other proteins like beta-amyloid in Alzheimer's or oncogenes in cancer which can lead to pathological states. Understanding PSMB1's function can aid in developing therapeutic strategies targeting proteostasis-related disorders.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46854155206825,"sku":"ab196623","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab196623","provider":"Iright","version":"1.0","type":"link"}
