Anti-Wnt family member 3 antibodies are used in the immunodetection of the protein encoded by the WNT3 gene. In humans, the canonical protein has a reported length of 355 amino acid residues and a mass of 39.6 kDa. Its subcellular localization is in the extracellular matrix and is also secreted. A member of the Wnt protein family, it is known to be involved with axon guidance and the Wnt signaling pathway. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include TETAMS, proto-oncogene Wnt-3, WNT-3 proto-oncogene protein, proto-oncogene Int-4 homolog, wingless-type MMTV integration site family, member 3, and INT4.
