Dapper homolog 1, an ortholog of Xenopus Dpr, antagonizes Wnt signaling by promoting Dvl degradation via a lysosome inhibitor-sensitive and proteasome inhibitor-insensitive mechanism. Dapper homolog 1 acts as an interacting protein for Dvl, and the interaction is formed between the DEP (Dishevelled, Egl-10, and pleckstrin) domain of Dvl and the central and C-terminal regions of Dapper homolog 1. The gene for human Dapper homolog 1 is localized on chromosomal region 14q23.1. The protein impedes the degradation of CTNNB1/beta-catenin, thereby enhancing the transcriptional activation of target genes of the Wnt signaling pathway. The protein is also required for normal notochord formation and is downregulated in hepatocellular carcinomas (HCC). It is expressed in human liver and various other tissues. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Human, mouse and rat brain lysate Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
