Participates in Wnt signaling by binding to the cytoplasmic C-terminus of frizzled family members and transducing the Wnt signal to down-stream effectors. Plays a role both in canonical and non-canonical Wnt signaling. Plays a role in the signal transduction pathways mediated by multiple Wnt genes. Required for LEF1 activation upon WNT1 and WNT3A signaling.
Specificity
Natural and recombinant Human Segment polarity protein dishevelled homolog DVL-1
Subcellular Location
Cell membrane Peripheral membrane protein Cytoplasmic side Cytoplasm cytosol Cytoplasmic vesicle Localizes at the cell membrane upon interaction with frizzled family members.
Interacts with CXXC4. Interacts (via PDZ domain) with NXN (By similarity). Interacts with BRD7 and INVS. Interacts through its PDZ domain with the C-terminal regions of VANGL1, VANGL2 and CCDC88C/DAPLE. Interacts with ARRB1; the interaction is enhanced by phosphorylation of DVL1. Interacts with CYLD (By similarity). Interacts (via PDZ domain) with RYK. Self-associates (via DIX domain) and forms higher homooligomers. Interacts (via PDZ domain) with DACT1 and FZD7, where DACT1 and FZD7 compete for the same binding site.
