This protein plays a role in PKR activation stimulating its autophosphorylation. Structurally PACT has a molecular mass of approximately 37 kDa. Researchers observed its expression in many tissues with notable presence in the brain and in immune cells. PACT functions interact with PKR and it also goes by the alternative names PKR activator and PKR protein activator.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPACT involves in the cellular stress response signaling. It serves as an activator for PKR a kinase that becomes active during viral infections and stress. PACT forms complexes with PKR facilitating its activation and subsequent initiation of downstream signaling cascades. It contributes significantly to the regulation of protein synthesis and cell growth by modulating these pathways. In conditions of stress PACT ensures adequate PKR activation for host defense.\u003cbr\u003e\nPathways\u003cbr\u003e\nPACT is key in the interferon signaling pathway and the stress response pathway. It partners with PKR to suppress protein synthesis through phosphorylation of the eukaryotic initiation factor 2 alpha (eIF2α) which slows down protein production during cellular stress. This interaction places PACT at a junction of antiviral defense and stress adaptation with PKR serving as an essential protein involved in these pathways.\u003cbr\u003e\nPACT links to conditions such as Huntington’s disease and dystonia. Dysregulation in PACT's function impacts these neurodegenerative disorders as it relates to its role in stress response. Altered interactions between PACT and PKR contribute to neuronal dysfunction highlighting its importance in these pathologies. Understanding how PACT and its partner proteins like PKR and eIF2α operate can lead to potential therapeutic targets for these diseases.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848595951785,"sku":"ab31967","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab31967","provider":"Iright","version":"1.0","type":"link"}
