Enzyme Information
| 2.7.11.10 |
I-kappa-B kinase.
based on mapping to UniProt O14920
ATP + [I-kappa-B protein] = ADP + [I-kappa-B phosphoprotein].
-!- Phosphorylates I-kappa-B proteins at specific serine residues, which marks them for destruction via the ubiquitination pathway. -!- Subsequent degradation of the I-kappa-B complex (IKK) activates NF-kappa-B, a translation factor that plays an important role in inflammation, immunity, cell proliferation and apoptosis. -!- If the serine residues are replaced by threonine residues, the activity of the enzyme is decreased considerably. -!- Formerly EC 2.7.1.37.
