产品介绍 background:
PKR is an interferon-inducible serine/threonine specific protein kinase. It is widely expressed in eukaryotic organisms and activated by double stranded RNA. Activation of PKR by dsRNAs leads to autophosphorylation at multiple sites. Phosphorylation of Thr446 and Thr451 in the PKR activation loop is required in vivo and in vitro for high level kinase activity. PKR phosphorylates its natural substrate, the alpha subunit of eukaryotic protein synthesis initiation factor 2 (EIF2 alpha), leading to the inhibition of protein synthesis. PKR is also involved in TLR signaling and mediates apoptosis in fibroblasts in response to viral infection and inflammatory cytokines, and also activates IKK and NFKB, thereby suppressing apoptosis. Recently, it has been reported that PKR also phosphorylates human p53 on serine 392. PKR might play a role in ER stress-induced apoptosis and in Alzheimer's disease. Alzheimer cases show prominent PKR activation in association with neuritic plaques and pyramidal neurons in the hippocampus and neocortex.

Function:
Following activation by double-stranded RNA in the presence of ATP, the kinase becomes autophosphorylated and can catalyze the phosphorylation of the translation initiation factor EIF2S1, which leads to an inhibition of the initiation of protein synthesis. Double-stranded RNA is generated during the course of a viral infection. In adddition to serine/threonine-protein kinase activity, also has tyrosine-protein kinase activity: phosphorylates CDK1 upon DNA damage. CDK1 phosphorylation triggers CDK1 polyubiquitination and subsequent proteolysis, thus leading to G2 arrest

Subunit:
Homodimer. Interacts with STRBP (By similarity). Interacts with DNAJC3. Inhibited by direct interaction with viral proteins such as HCV E2, HCV NS5A and influenza A NS1. Activated by the interaction with HIV-1 Tat (By similarity). Forms a complex with FANCA, FANCC, FANCG and HSP70.

Post-translational modifications:
Autophosphorylated on several Ser and Thr residues. Autophosphorylation of Thr-451 is dependent on Thr-446 and is stimulated by dsRNA binding and dimerization. Autophosphorylation apparently leads to the activation of the kinase.

Similarity:
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily. 
Contains 2 DRBM (double-stranded RNA-binding) domains. 
Contains 1 protein kinase domain.

PKR是一种干扰素诱导的丝氨酸/苏氨酸特异性蛋白激酶。它在真核生物中广泛表达,并被双链RNA激活。激活的PKR由dsRNA导致在多个位点的自***酸化。PKR激活环中的Trx46和Tr451的***酸化需要体内和体外的高水平激酶活性。PKR***酸化其天然底物,即真核蛋白质合成起始因子2(EIF2α)的α亚基,从而导致蛋白质合成的抑制。PKR还参与TLR信号转导,介导成纤维细胞在病毒感染和炎性细胞因子作用下的凋亡,并激活IKK和NFKB,从而抑制细胞凋亡。最近,已经报道PKR还对丝氨酸392***酸化人p53。PKR可能在ER应激诱导的细胞凋亡和阿尔茨海默病中发挥作用。阿尔茨海默病患者表现出明显的PKR激活,与神经炎斑块和锥体痣有关。
