| Sysname |
ATP:[IkappaB protein] phosphotransferase
|
| Reaction(IUBMB) |
ATP + [IkappaB protein] = ADP + [IkappaB phosphoprotein]
|
| Reaction(KEGG) |
|
| Substrate |
ATP [CPD: C00002];
[IkappaB protein]
|
| Product |
ADP [CPD: C00008];
[IkappaB phosphoprotein]
|
| Comment |
The enzyme phosphorylates IkappaB proteins at specific serine residues, which marks them for destruction via the ubiquitination pathway. Subsequent degradation of the IkB complex (IKK) activates NF-kappaB, 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.
