HLA-G - major histocompatibility complex, class I, G Gene
Also Known as MHC-G
Species: Homo sapiens
About HLA-G
This gene has 7 transcripts (splice variants), 1 gene allele, 560 orthologues, 22 paralogues and is associated with 1 phenotype. Broad expression in placenta (RPKM 29.5), colon (RPKM 14.0) and 15 other tissues.
Summary
HLA-G belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. HLA-G is expressed on fetal derived placental cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the alpha1 and alpha2 domain, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exon 6 encodes the cytoplasmic tail.
