Antibodies / Antibodies-Dickkopf Proteins

-20°C

Supplied as a lyophilized powder in PBS. Reconstitute with 200ul sterile PBS.

Recombinant protein corresponding to mouse Dkk-3.

DKK3, like DKK1, DKK2, and DKK4, possesses an N-terminal signal peptide and 2 conserved cysteine-rich domains, which are separated by a linker region and contain 10 cysteine residues each. The second cysteine region has a putative lipid-binding function that may facilitate WNT/DKK interactions at the plasma membrane. The linker region contains 50-55aa in DKK1, DKK2, and DKK4, whereas in DKK3 it contains only 12aa. All DKKs have several potential sites for cleavage by furin-type proteases. Northern blot analysis revealed wide expression of the DKK3 transcript, with highest expression in heart, brain, and spinal cord. In situ hybridization reveals highest expression in mouse brain, eye, and heart.
