  • Function

    Cytokine that may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. Down-regulates the BMP4 signaling in a dose-dependent manner. Acts as inhibitor of monocyte chemotaxis.
  • Tissue specificity

    Highly expressed in small intestine, fetal brain and colon. Expression is restricted to intestinal subepithelial myofibroblasts (ISEMFs) at the crypt base. In subjects with HMPS1, by contrast, GREM1 is expressed, not only in basal ISEMFs, but also at very high levels in epithelial cells (predominantly colonocytes), with expression extending most of the way up the sides of the crypt. Weakly expressed in brain, ovary, prostate, pancreas and skeletal muscle. In brain found in the region localized around the internal capsule in the large subcortical nuclei, including caudate, putamen, substantia nigra, thalamus and subthalamus. Predominantly expressed in normal cells including neurons, astrocytes and fibroblasts.
  • Involvement in disease

    Polyposis syndrome, mixed hereditary 1
  • Sequence similarities

    Belongs to the DAN family.
    Contains 1 CTCK (C-terminal cystine knot-like) domain.
  • Cellular localization

  • Information by UniProt


  • SDS-PAGE analysis of ab220546 stained overnight with Coomassie Blue.

    The protein migrates as 28-35 kDa on a SDS-PAGE gel under reducing conditions due to glycosylation.

  • Immobilized Human BMP-2, Tag Free at 2 μg/ml (100 μl/well) can bind ab220546 with a linear range of 0.8-81.9 ng/ml.
