Product Specific Information

Description: Wnt proteins constitute a family of secreted glyocoproteins that activate signal transduction pathways to mediate tissue homeostasis, cell fate, cell proliferation, and self-renewal. The canonical signaling pathway is initiated upon Wnt binding to a Frizzled family receptor and an LRP5/LRP6 coreceptor, which leads to activation of the beta-catenin cascade. Non-canonical Wnt signals are activated by binding to a Frizzled family receptor and ROR2 coreceptor. Extensive research has shown that deregulation of these pathways or its components can lead to cancer.

Human Wnt-1 is encoded as a 370 amino acid precursor that, upon secretion, is cleaved into a 343 amino acid (42 kDa) mature form. At the amino acid level, mature human Wnt-1 is approximately 99% identical to mature mouse Wnt-1. Depending on the tissue, Wnt-1 can activate the canonical and non-canonical signaling pathways. Studies have demonstrated its involvement in a variety of functions, including embryonic development and carcinogenesis. Wnt-1 signaling can also induce the phosphorylation and subsequent degradation of c-Myb.

Applications Reported: Recombinant human Wnt-1 is biologically active and can enhance BMP-induced alkaline phosphatase production by murine ATDC5 cells.

Applications Tested: The ED50 of this protein, as determined by human BMP-2 (200 ng/mL) induction of alkaline phosphatase production by murine ATDC5 cells, is 1.5-2.5 ng/mL.

Source: E. coli (amino acids Ala28-Leu370; accession # NP_005421).

Bioactivity: The ED50 of this protein, as determined by human BMP-2 (200 ng/mL) induction of alkaline phosphatase production by murine ATDC5 cells, is 1.5-2.5 ng/mL.

Endotoxin: Less than 0.1 ng/ug cytokine as determined by the LAL assay. Purity: >98% as determined by SDS-PAGE and HPLC.

Molecular Weight: 42 kDa (mature form).

Storage and handling: For best recovery, quick spin vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. Use in sterile environment. Store lyophilized protein at less than or equal to -20°C. Reconstituted protein solution can be stored with carrier-protein (e.g., 0.1% BSA) at less than or equal to -20°C.
