  • Synonym
    GARP,Garpin,D11S833E
  • Source
    Human LRRC32, Fc Tag(LR2-H5256) is expressed from human 293 cells (HEK293). It contains AA His 20 - Asn 627 (Accession # Q14392-1).
    Predicted N-terminus: His 20
  • Molecular Characterization
    LRRC32 Structure

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 92.4 kDa. The protein migrates as 105 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.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

  • Background
    Leucine-rich repeat protein 32 (LRRC32), also known as GARP (glycoprotein A repetitions predominant). LRRC32 expression promotes the acquisition of a Treg phenotype including reduced cellular proliferation, reduced cytokine secretion, and the capacity to suppress the proliferation of naïve T cells. LRRC32 binds directly to the TGF-beta latency associated peptide (LAP) and tethers latent TGF-beta on the surface of activated Treg cells. The presentation of TGF-beta on Tregs contributes to their ability to suppress naïve T cell proliferation.
