Protein attributes

Sequence length	636 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Transcriptional activator; DNA-binding protein that specifically recognize the sequence 5'-YAAC[GT]G-3'. Plays an important role in the control of proliferation and differentiation of hematopoietic progenitor cells.
Subunit structure	Interacts with HIPK2, MAF, MYBBP1A and NLK. Ref.13 Ref.14 Ref.15 Ref.16
Subcellular location	Nucleus.
Domain	Comprised of 3 domains; an N-terminal DNA-binding domain, a centrally located transcriptional activation domain and a C-terminal domain involved in transcriptional repression. Ref.10 Ref.11 Ref.12 C-terminal truncated mutants display increased transactivation. Ref.10 Ref.11 Ref.12
Post-translational modification	Ubiquitinated; mediated by SIAH1 and leading to its subsequent proteasomal degradation By similarity. Phosphorylated by NLK on multiple sites, which induces proteasomal degradation.
Sequence similarities	Contains 3 HTH myb-type DNA-binding domains.
