  • Source
    Human ZNRF3, His Tag (ZN3-H52H3) is expressed from human 293 cells (HEK293). It contains AA Lys 56 - Met 219 (Accession # Q9ULT6-1).
    Predicted N-terminus: Lys 56
  • Molecular Characterization
    Online(Lys 56 - Met 219) Q9ULT6-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 19.7 kDa. The protein migrates as 22-25 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Background
    The transmembrane E3 ubiquitin ligase zinc and ring finger 3 (ZNRF3) is a negative feedback regulator of Wnt signalling. ZNRF3 is associated with the Wnt receptor complex, and inhibits Wnt signalling by promoting the turnover of frizzled and LRP6 and acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway.
