Role in NF-κB Signaling:
IKBKG (NEMO) is a regulatory subunit of the IKK complex, which phosphorylates IκB proteins, leading to their degradation and NF-κB activation. Phosphorylation at Ser85 enhances NEMO’s interaction with ATM kinase, enabling downstream signaling .
Mutations in IKBKG are linked to immunodeficiencies (e.g., ectodermal dysplasia, recurrent infections) .
The antibody aids in studying how phosphorylation modulates NEMO’s function in these contexts .
Ser85 phosphorylation is induced by genotoxic stress (e.g., UV radiation) and ATM activation .
Cross-talk with ubiquitination (e.g., K63-linked chains) regulates NF-κB activation .
