Xenopus Dickkopf （Dkk）-1 was initially discovered as a Wnt antagonist that plays an important role in head formation. By far，four members of Dkk have been identified in mammals. Each Dkk molecule contains two conserved cysteine-rich domains. Recent studies showed that the second Cys-rich domains of Dkk1 and Dkk2 inhibited Wnt-3a-activated signaling，whereas the first Cys-rich domains had no effects. In addition，the second Cys-rich domain of Dkk-2，but not that of Dkk-1，was able to activate the canonical pathway in the presence of LRP6，and this LRP-dependent signaling does not require Dvl.
應用類型
Western blotting （0.5-4 ug/ml）. However， the optimal conditions should be determined individually. The antibody recognizes 30-35 kDa Dkk2 in samples from human， mouse and rat origins. A ~25 kDa band can also be detected， presumably to be the cleavage fragment of Dkk2.
