HLA-C belongs to the MHC (human = HLA) class I heavy chain receptors. The C receptor is a heterodimer consisting of a HLA-C mature gene product and β2-microglobulin. The mature C chain is anchored in the membrane. MHC Class I molecules, like HLA-C, are expressed in nearly all cells, and present small peptides to the immune system which surveys for non-self peptides.

HLA-C is a locus on chromosome 6 that encodes for a large number of HLA-C alleles that are Class-I MHC receptors. HLA-C is localized proximal to the HLA-B locus is located on the distal end of the HLA region. Most HLA Cw:B haplotypes are in strong linkage disequilibrium and many are as ancient as the human species itself.
