Human CD5 signaling and constitutive phosphorylation of C-terminal serine residues by casein kinase II.
CD5 is a lymphocyte surface glycoprotein with a long cytoplasmic domain suitable for phosphorylation and signal transduction, which is involved in the modulation of Ag-specific receptor-mediated activation and differentiation signals. In this study, we use Jurkat T cell transfectants of CD5 cytoplasmic tail mutants to reveal phosphorylation sites relevant to signal transduction. Our results sho...
متن کاملInhibition of I kappa B-alpha phosphorylation and degradation and subsequent NF-kappa B activation by glutathione peroxidase overexpression
We report here that both kappa B-dependent transactivation of a reporter gene and NF-kappa B activation in response to tumor necrosis factor (TNF alpha) or H2O2 treatments are deficient in human T47D cell transfectants that overexpress seleno-glutathione peroxidase (GSHPx). These cells feature low reactive oxygen species (ROS) levels and decreased intracellular ROS burst in response to TNF alph...
متن کاملPhosphorylation of RIG-I by casein kinase II inhibits its antiviral response.
RIG-I is an intracellular RNA virus sensor that mediates a signaling pathway that triggers the alpha/beta interferon (IFN-α/β) immune defenses. However, the mechanism for regulation of RIG-I activity remains largely unknown. Here we show that RIG-I activity is regulated by phosphorylation and dephosphorylation in its repressor domain (RD). Threonine at amino acid (aa) 770 and serine at aa 854 t...
متن کاملPhosphorylation of fibrinogen by casein kinase 1.
Casein kinase 1 phosphorylated human fibrinogen, in a reaction that did not use GTP as phosphoryl donor and was neither stimulated by cyclic AMP or Ca2+, nor inhibited by the cyclic AMP-dependent protein kinase inhibitor protein. Maximal incorporation averaged 4 mol of phosphate per mol of fibrinogen, most of it in the largest CNBr-fragment of the alpha-chain. Phosphoamino acid analysis reveale...
متن کاملHypothermia enhances phosphorylation of I kappa B kinase and prolongs nuclear localization of NF-kappa B in LPS-activated macrophages
Hypothermia (HT) has been associated with both beneficial and detrimental consequences in various pathophysiologic states. While HT is generally thought to have anti-inflammatory and cytoprotective effects, we have previously shown that moderate in vitro HT prolongs TNFα production by LPS-stimulated mononuclear phagocytes, in part by prolonging TNFα gene transcription and activation of the plei...
