Quality Standard:【产品介绍】HLA-B 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. Class I molecules play a central role
in the immune system by presenting peptides derived from
the endoplasmic reticulum lumen. They are expressed
in nearly all cells. The heavy chain is approximately
45 kDa and its gene contains 8 exons. Exon 1 encodes
the leader peptide; exon 2 and 3 encode the alpha1
and alpha2 domains, which both bind the peptide; exon
4 encodes the alpha3 domain; exon 5 encodes
the transmembrane region; and exons 6 and 7 encode
the cytoplasmic tail. Polymorphisms within exon 2 and exon
3 are responsible for the peptide binding specificity
of each class I molecule. Typing for these polymorphisms
is routinely done for bone marrow and
kidney transplantation. Hundreds of HLA-B alleles have
been described.
