General annotation (Comments)

Function

Inhibits the transactivation activity of the Myod family of myogenic factors and represses myogenesis. Acts by associating with Myod family members and retaining them in the cytoplasm by masking their nuclear localization signals. Can also interfere with the DNA-binding activity of Myod family members. Plays an important role in trophoblast and chondrogenic differentiation. Regulates the transcriptional activity of TCF7L1/TCF3 by interacting directly with TCF7L1/TCF3 and preventing it from binding DNA. Binds to the axin complex, resulting in an increase in the level of free beta-catenin. Affects axin regulation of the WNT and JNK signaling pathways By similarity.

Subunit structure

The C-terminus interacts with AXIN1 and LEF1 By similarity.

Subcellular location

Nucleus By similarity. Cytoplasm By similarity.

Sequence similarities

Belongs to the MDFI family.
