  • Synonym
    BTN3A1,CD277,BTF5
  • Source
    Human BTN3A1 Protein, His Tag(BT1-H52H4) is expressed from human 293 cells (HEK293). It contains AA Gln 30 - Gly 254 (Accession # O00481-1).
    Predicted N-terminus: Gln 30
  • Molecular Characterization

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

    The protein has a calculated MW of 29.5 kDa. The protein migrates as 32-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

  • Background
    Butyrophilin subfamily 3 member A1 (BTN3A1) is also known as CD277 and BTF5, which belongs to the immunoglobulin superfamily and contains one B30.2/SPRY domain and two Ig-like V-type (immunoglobulin-like) domains. BTN3A1 plays a role in T-cell activation and in the adaptive immune response. Also, BTN3A1 regulates the proliferation of activated T-cells and the release of cytokines and IFNG by activated T-cells. Furthermore, BTN3A1 mediates the response of T-cells toward infected and transformed cells that are characterized by high levels of phosphorylated metabolites, such as isopentenyl pyrophosphate.
