Human HLA-G Recombinant Protein (N-GST) (GXRP01077)

Human HLA-G Recombinant Protein (N-GST)

Human HLA-G Recombinant Protein (N-GST) is a recombinant protein expressed in E. coli, spanning Met29-His117, with an N-terminal GST tag. Predicted molecular weight: 37.28 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. HLA class I histocompatibility antigen, alpha chain G (HLA-G) is a ~38 kDa protein. Non-classical major histocompatibility class Ib molecule involved in immune regulatory processes at the maternal-fetal interface. For research use only.

In complex with B2M/beta-2 microglobulin binds a limited repertoire of nonamer self-peptides derived from intracellular proteins including histones and ribosomal proteins. Peptide-bound HLA-G-B2M complex acts as a ligand for inhibitory/activating KIR2DL4, LILRB1 and LILRB2 receptors on uterine immune cells to promote fetal development while maintaining maternal-fetal tolerance. Upon interaction with KIR2DL4 and LILRB1 receptors on decidual NK cells, it triggers NK cell senescence-associated secretory phenotype as a molecular switch to promote vascular remodeling and fetal growth in early pregnancy. Through interaction with KIR2DL4 receptor on decidual macrophages induces pro-inflammatory cytokine production mainly associated with tissue remodeling.
