It weighs approximately 78 kDa hence the name GRP78. This chaperone protein binds to hydrophobic regions of nascent polypeptides to prevent aggregation and misfolding. GRP78 is expressed in high levels in the ER of cells where it monitors cellular stress and aids in maintaining ER homeostasis.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nGRP78\/BiP is important in the unfolded protein response (UPR) a cellular stress response related to the ER. It is part of a complex that manages protein load inside the ER by regulating the fold of nascent proteins and interacting with other ER stress sensors like IRE1 PERK and ATF6. This function is essential for maintaining proper protein conformation in the ER especially during physiological stress ensuring that only correctly folded proteins proceed to the Golgi apparatus.\u003cbr\u003e\nPathways\u003cbr\u003e\nGRP78\/BiP significantly affects the UPR and apoptosis pathways. By controlling protein folding and quality in the ER GRP78 helps prevent cell death under stress conditions. It works closely with other proteins like ATF6 which activates stress response genes. In normal conditions GRP78 keeps stress transducers inactivated but during stress it dissociates allowing UPR signaling to occur.\u003cbr\u003e\nGRP78\/BiP has been implicated in cancer and neurodegenerative diseases. Overexpression of GRP78 is associated with tumor proliferation and poor prognosis in various cancers as cancer cells heavily rely on its protein-folding capacity to survive. Additionally in neurodegenerative diseases misfolded proteins can accumulate leading GRP78 to attempt counteracting these toxic aggregations highlighting its connection with proteins like tau and amyloid-beta in diseases such as Alzheimer's.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843540766889,"sku":"ab302765","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab302765","provider":"Iright","version":"1.0","type":"link"}
