Researchers commonly identify it by its phosphorylation state in western blots recognizable as phospho-PERK or p-PERK. The molecular weight of PERK is approximately 125 kDa. It is predominantly expressed in the endoplasmic reticulum (ER) of cells acting as a sensor for misfolded proteins. PERK acts mechanistically by phosphorylating the translation initiation factor eIF2α reducing overall protein synthesis and alleviating ER stress.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPERK plays an important role in maintaining cellular homeostasis during stress conditions. It forms part of a larger complex that regulates the adaptive response to ER stress. Upon activation PERK arrests general protein translation while allowing for selective translation of stress response proteins. This mechanism prevents the accumulation of unfolded proteins and assists in the survival of cells under adverse conditions. PERK also contributes to the regulation of oxidative stress and cell apoptosis adding further layers to its biological significance.\u003cbr\u003e\nPathways\u003cbr\u003e\nPERK's activity intersects with the integrated stress response and UPR pathways. It shares a close functional relationship with proteins like ATF4 which is synthesized upon PERK activation and is important for the transcription of genes related to stress adaptation. The UPR pathway coordinates with the IRE1 and ATF6 pathways forming an important network for managing ER stress. These pathways collectively ensure cellular resilience adjusting metabolic demands and promoting cellular recovery.\u003cbr\u003e\nPERK's malfunction can contribute to conditions such as diabetes and neurodegenerative diseases like Alzheimer's. In diabetes improper regulation of PERK affects insulin synthesis and secretion leading to pancreatic Β-cell dysfunction. Alzheimer's disease shows links with heightened ER stress and dysregulation of the PERK-eIF2α signaling pathway potentially contributing to neuronal death. PERK dysfunction can also associate with other proteins such as CHOP which mediates apoptosis during prolonged ER stress exacerbating these conditions.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46844071018665,"sku":"ab229912","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab229912","provider":"Iright","version":"1.0","type":"link"}
