Entrez ID 3105
Gene name Major histocompatibility complex, class I, A
Gene symbol HLA-A
Synonyms (NCBI Gene)
HLAA
Chromosome 6
Chromosome location 6p22.1
Summary HLA-A 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
