It physically interacts with PKR and inhibits its activation and activity (1). Influenza virus activates p58IPK and thus blocks the activity of PKR to repress translation in the infected cells. In the uninfected cells, p58IPK forms a complex with its own inhibitor, HSP40, and is kept in an inactive state (2). ER stress induces the expression of p58IPK mediated by ATF6 (3,4). The induced p58IPK negatively regulates Perk activity, inhibits eIF2α phosphorylation and suppresses the activation of expression of downstream ER-responsive genes ATF4 and GADD153 (4). More recently, p58IPK has been shown to associate with the lumen of the endoplasmic reticulum (ER) where it is believed to serve as a cochaperone for BiP (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nACPHD; DnaJ (Hsp40) homolog, subfamily C, member 3; DnaJ heat shock protein family (Hsp40) member C3; DnaJ homolog subfamily C member 3; DNAJC3; DNJC3; Endoplasmic reticulum DNA J domain-containing protein 6; ER-resident protein ERdj6; ERdj6; FLJ21288; HP58; Interferon-induced, double-stranded RNA-activated protein kinase inhibitor; P58; p58(IPK); P58IPK; PRKRI; Protein kinase inhibitor of 58 kDa; Protein kinase inhibitor p58; protein-kinase, interferon-inducible double stranded RNA dependent inhibitor\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M Mk\nSENSITIVITY: Endogenous\nMW (kDa): 58\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798060388521,"sku":"2940S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2940s","provider":"Iright","version":"1.0","type":"link"}
