FcRn, FCGRT & B2M

Source

Human FCGRT&B2M Heterodimer Protein, Strep Tag&Tag Free (FCM-H5283) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # P55899-1 (FCGRT) & P61769-1 (B2M)).

Predicted N-terminus: Ala 24 (FCGRT) & Ile 21 (B2M)

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

Human FCGRT&B2M Heterodimer Protein, Twin-Strep Tag&Tag Free, produced by co-expression of FCGRT and B2M, has a calculated MW of 33.8 kDa (FCGRT) and 11.7 kDa (B2M). Subunit FCGRT is fused with Twin-Strep tag at the C-terminus and subunit Beta-2 microglobulin (B2M) contains no tag. The reducing (R) protein migrates as 40-43 kDa (FCGRT) and 12 kDa (B2M) when calibrated against Star Ribbon Pre-stained Protein Marker respectively due to glycosylation.

Background

FCGRT & B2M heterodimer protein (FcRn complex) consist of two subunits: p51 (equivalent to FCGRT), and p14 (equivalent to beta-2-microglobulin), and forms an MHC class I-like heterodimer. Fc fragment of IgG, receptor, transporter, alpha (FCGRT) binds to the Fc region of monomeric immunoglobulins gamma and mediates the uptake of IgG from milk. FCGRT possible role in transfer of immunoglobulin G from mother to fetus. Beta-2-microglobulin (B2M) is a component of the class I major histocompatibility complex (MHC) and involved in the presentation of peptide antigens to the immune system.
