In the current studies we sought to identify novel ER stress-induced genes by conducting microarray analysis on tunicamycin-treated cells. We identified P58(IPK), an inhibitor of the interferon-induced double-stranded RNA-activated protein kinase, as induced during ER stress. Additional studies suggested that p58(IPK) induction was mediated via ATF6 and that P58(IPK) played a role in down-regulating the activity of the pancreatic eIF2 kinase/eukaryotic initiation factor 2alpha (eIF2alpha)-like ER kinase/activation transcription factor (ATF) 4 pathway. Modulation of P58(IPK) levels altered the phosphorylation status of eIF2alpha, and thereby affected expression of its downstream targets, ATF4 and Gadd153. Overexpression of P58(IPK) inhibited eIF2alpha phosphorylation and reduced ATF4 and Gadd153 protein accumulation, whereas silencing of P58(IPK) expression enhanced pancreatic eIF2alpha-like ER kinase and eIF2alpha phosphorylation and increased ATF4 and Gadd153 accumulation. These findings implicate P58(IPK) as an important component of a negative feedback loop used by the cell to inhibit eIF2alpha signaling, and thus attenuate the unfolded protein response."xsd:string |
