Protein attributes

Sequence length	838 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Inhibitor of the Wnt signaling pathway. Down-regulates beta-catenin. Probably facilitate the phosphorylation of beta-catenin and APC by GSK3B By similarity.
Subunit structure	Interacts with SMAD7 and RNF111. Interacts with ANKRD6 By similarity. Interacts with glycogen synthase kinase-3 beta (GSK3B) and beta-catenin. The interaction between axin and beta-catenin occurs via the armadillo repeats contained in beta-catenin.
Subcellular location	Cytoplasm.
Tissue specificity	Expressed in lung and thymus. Ref.1
Post-translational modification	Probably phosphorylated by GSK3B and dephosphorylated by PP2A.
Sequence similarities	Contains 1 DIX domain. Contains 1 RGS domain.
