ABSTRACT:
The present invention relates, in general, to a kinase which in its activated state is capable of site-specific phosphorylation of I.kappa.B.alpha., I.kappa.B.alpha. kinase. In particular, the present invention relates to the purified- kinase, purified polypeptide subunits of the kinase, nucleic acid molecules coding for the purified polypeptide subunits; recombinant nucleic acid molecules; cells containing the recombinant nucleic acid molecules; antibodies having binding affinity specifically to the kinase or its polypeptide subunits; hybridomas containing the antibodies; nucleic acid probes for the detection of the nucleic acid encoding the kinase; a method of detecting nucleic acids encoding the kinase or polypeptides of the kinase in a sample; and kits containing nucleic acid probes or antibodies. This invention further relates to bioassays using the nucleic acid sequence, protein or antibodies of this invention to diagnose, assess, or prognose a mammal afflicted with an undesired activation of NF-.kappa.B. This invention also relates to ligands, agonists, and antagonists of the kinase, and diagnostic and therapeutic uses thereof. This invention also relates to bioassays using the kinase or polypeptides of the kinase of this invention to identify ligands, agonists, and antagonists. More specifically, this invention relates to selective inhibitors of the kinase and to structure-based design of ligands, agonists, and antagonists of the kinase. This invention further relates to gene therapy using the nucleic acids of the invention.
