Topics Covered

• Ubiquitination is a reversible covalent modification, akin to phosphorylation
• Ubiquitination regulates protein kinase activity through proteasome-independent mechanisms
• K63-linked polyubiquitination activates TAK1 and IKK in the NF-kappaB pathway
• Deubiquitination enzymes inhibit protein kinases in the NF-kappaB pathway
• Protein kinase regulation by ubiquitin is important in innate and adaptive immunity
