Gene Gene information from NCBI Gene database.
Entrez ID 3106
Gene name Major histocompatibility complex, class I, B
Gene symbol HLA-B
Synonyms (NCBI Gene)
ASB-4901HLAB
Chromosome 6
Chromosome location 6p21.33
Summary 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
