Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Adapter linking MAP3K7/TAK1 and TRAF6 or TRAF2. Mediator of MAP3K7 activation, respectively in the IL1 and TNF signaling pathways. Plays a role in activation of NF-kappa-B and AP1 transcription factor. Isoform 2 may be an oncogenic factor. Ref.1 Ref.3
Subunit structure	Interacts with TAB1, TAB2, MAP3K7, TRAF2 and TRAF6. The minimal TAB3-containing complex (TAB1-MAP3K7-TAB3) appears not to contain TAB2. However, it seems sensible to consider that TAB2 may also join this complex and may act in a cooperative manner with TAB3. Ref.1 Ref.3 Ref.2
Tissue specificity	Widely expressed. Constitutively overexpressed in certain tumor tissues. Isoform 1 is a major transcript while isoform 2 is a minor transcript. Ref.3 Ref.2
Post-translational modification	Phosphorylated. Ref.1 Ref.2 Ref.6 Ubiquitinated; following IL1 stimulation or TRAF6 overexpression. Ref.1
Sequence similarities	Contains 1 CUE domain. Contains 1 RanBP2-type zinc finger.
