IUBMB Comments
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.

GENERAL INFORMATION

UNIPROT
COMMENTARY hide
LITERATURE
physiological function
the IkappaB kinase complex catalyses the phosphorylation of IkappaBalpha at Ser32 and Ser36, essential for signaling the subsequent ubiquination and protosomal degradation of IkappaBalpha, thus leaving the NF-kappaB free to translocate to the nucleus and activate pro-inflammatory gene transcription
