[Back to Kinase NIK]
Substrate: IKBKB

Description: Inhibitor of nuclear factor kappa-B kinase subunit beta (EC beta) (IkBKB) (IKK-beta) (IKK-B) (I-kappa-B kinase2) (IKK2) (Nuclear factor NF-kappa-B inhibitor kinase beta) (NFKBIKB).

Synonyms: IKKB

Ensembl ID: ENSG00000104365

UniprotKB/SwissProt: IKKB_HUMAN (O14920)

Function: Phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. Also phosphorylates NCOA3 (By similarity).

Other Modifications: View all modification sites in dbPTM
