CC   -!- FUNCTION: Participates in the Wnt signaling pathway. Binds to DNA and
CC       acts as a repressor in the absence of ctnnb1-A and possibly ctnnb1-B,
CC       and as an activator in the presence of these proteins. Required early
CC       in development for the establishment of the dorsal body axis in
CC       response to maternal Wnt signaling (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with csnk1e, ctnnb1-A, ctbp-B, dact1-A and gsk3b.
CC       May interact with ase and tle4-A (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00267}.
CC   -!- PTM: Phosphorylated. Phosphorylation by csnk1e promotes binding to
CC       ctnnb1-A while phosphorylation by gsk3b may reverse this effect (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the TCF/LEF family. {ECO:0000305}.
