Abstract: The invention provides a means for reconstituting I?B kinase in yeast in order to study the structure and regulation of IKK and to produce pharmacological therapies to block IKK. This invention can be used to express an IKK complex that is biochemically identical to IKK isolated from native cells and in coupled in vitro kinase assays to screen for its upstream regulators. The IKK expressed by reconstituting the yeast can be used to screen for unknown substrates and for pharmacological therapies that block its activity. The invention could also be used to screen for compounds that enhance its activity. The IKK may also be used as a source of material for crystallization and X-ray diffraction analysis.

Abstract: The present invention provides an isolated nucleic acid molecules encoding I?B kinase (IKK) catalytic subunit polypeptides, which are associated with an IKK serine protein kinase that phosphorylates a protein (I?B) that inhibits the activity of the NF-?B transcription factor, vectors comprising such nucleic acid molecules and host cells containing such vectors. In addition, the invention provides nucleotide sequences that can bind to a nucleic acid molecule of the invention, such nucleotide sequences being useful as probes or as antisense molecules. The invention also provides isolated IKK catalytic subunits, which can phosphorylate an I?B protein, and peptide portions of such IKK subunit. In addition, the invention provides anti-IKK antibodies, which specifically bind to an IKK complex or an IKK catalytic subunit, and IKK-binding fragments of such antibodies.
