Protein attributes

Sequence length	467 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Required for TLR4 activation of the MEK/ERK pathway. Able to activate NF-kappa-B 1 by stimulating proteasome-mediated proteolysis of NF-kappa-B 1/p105. Plays a role in the cell cycle By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium By similarity.
Subunit structure	Forms a ternary complex with NFKB1 and TNIP2 By similarity.
Subcellular location	Cytoplasm.
Tissue specificity	High in adult submandibular gland, thymus, spleen and newborn digestive tract.
Post-translational modification	Autophosphorylated By similarity.
Sequence similarities	Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. Contains 1 protein kinase domain.
