1 Investigation of guanine-nucleotide-binding protein involvement and regulation of cyclic AMP metabolism in interleukin 1 signal transduction. Guanine Nucleotides interleukin 1 complex Mus musculus
2 Investigation of guanine-nucleotide-binding protein involvement and regulation of cyclic AMP metabolism in interleukin 1 signal transduction. Cyclic AMP interleukin 1 complex Mus musculus
3 The involvement of guanine-nucleotide-binding proteins (G-proteins) and regulation of cyclic AMP (cAMP) in interleukin 1 (IL1) signal transduction has been investigated in EL4 and 7OZ/3 cells expressing Type 1 and Type 2 IL1 receptors respectively. Cyclic AMP interleukin 1 complex Mus musculus
4 In EL4-cell membrane preparations the kinetics of 125I-IL1 binding were altered in the presence of guanosine 5"-[beta gamma-imido]triphosphate, resulting in the formation of a higher-affinity state for IL1 binding. Guanylyl Imidodiphosphate interleukin 1 complex Mus musculus
5 In EL4-cell membrane preparations the kinetics of 125I-IL1 binding were altered in the presence of guanosine 5"-[beta gamma-imido]triphosphate, resulting in the formation of a higher-affinity state for IL1 binding. Guanylyl Imidodiphosphate interleukin 1 complex Mus musculus
6 These results suggest that IL1 receptor function may be regulated by guanine nucleotides; however, the mechanism appears to differ from that exhibited by conventional G-protein-linked receptors. Guanine Nucleotides interleukin 1 complex Mus musculus
