Contributes to the regulation of the Wnt signaling pathway. Down-regulates CTNNB1-mediated transcriptional activation of target genes, such as CCND1, and may thereby act as tumor suppressor. May be involved in dendritic cell and neuron differentiation (By similarity).
Subcellular locations: Cytoplasm, Cytoplasm, Perinuclear region, Cell projection, Growth cone
In neurons, seems to concentrate at axonal growth cone. Perinuclear in neurons (By similarity).
