  • OMIM 142871 - HLAG HLA-6.0; HLA60, T-CELL A LOCUS; TCA
    • Human leukocyte antigen (HLA)-G
    • The HLA-G gene is monomorphic and the only MHC antigen expressed on cytotrophoblast cells of placenta.
    • Extravillous trophoblasts from normal human placenta and the BeWo adherent human choriocarcinoma cell line express an unusual form of class I HLA molecule.
    • nonclassic HLA-G class I molecules in inhibiting natural killer cell function.
    • modulate the immunologic relationship between mother and fetus.
    • alternatively spliced HLA-G isoforms in first trimester trophoblast cell populations. Several alternatively spliced HLA-G mRNA isoforms, including a 14-bp polymorphism in the 3-prime UTR end (exon 8) of the HLA-G gene, are expressed at a significantly lower level than the corresponding HLA-G mRNA isoforms with the 14-bp sequence deleted. Hviid et al. (2003) suggested that this finding may have functional implications in connection with reports of aberrant HLA-G expression and reproductive success.
    • alternative splicing that generates seven HLA-G proteins.
  • UniProt P17693 338 AA
    • Involved in the presentation of foreign antigens to the immune system.
    • Plays a role in maternal tolerance of the fetus by mediating protection from the deleterious effects of natural killer cells, cytotoxic T-lymphocytes, macrophages and mononuclear cells.
