Protein attributes

Sequence length	396 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Down-regulates NF-kappa-B signaling by competing with RELA for CREBBP/EP300 binding. Involved in the microRNA (miRNA) biogenesis. Ref.4 Ref.12
Subunit structure	Binds SMAD4 and CREBBP/EP300. Binds the SMAD1/OAZ1/PSMB4 complex. Interacts with DROSHA. Ref.1 Ref.4 Ref.5 Ref.12
Subcellular location	Nucleus Ref.1.
Tissue specificity	Ubiquitous, with highest expression in heart and skeletal muscle. Ref.1
Post-translational modification	Degraded by the proteasome upon binding to the SMAD1/OAZ1/PSMB4 complex. Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.6 Ref.8 Ref.9 Ref.10 Ref.11 Ref.13 Ref.14
Sequence similarities	Contains 1 FHA domain.
