アプリケーション Abreviews 特記事項
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 28 kDa (predicted molecular weight: 31 kDa).Can be blocked with Human RSPO3 peptide (ab135941).


  • 機能Activator of the beta-catenin signaling cascade, leading to TCF-dependent gene activation. Acts both in the canonical Wnt/beta-catenin-dependent pathway, possibly via a direct interaction with Wnt proteins, and in a Wnt-independent beta catenin pathway through a receptor signaling pathway that may not use frizzled/LRP receptors. Acts as a ligand for frizzled FZD8 and LRP6. May negatively regulate the TGF-beta pathway.
  • 組織特異性Ubiquitously expressed. Expressed at higher level in placenta, small intestine, fetal thymus and lymph node.
  • 配列類似性Belongs to the R-spondin family.
    Contains 2 FU (furin-like) repeats.
    Contains 1 TSP type-1 domain.
  • ドメインThe FU repeats are required for activation and stabilization of beta-catenin.
