HLA-C
Encyclopedia
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, which 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.

Interactions

HLA-C has been shown to interact
Protein-protein interaction
Protein–protein interactions occur when two or more proteins bind together, often to carry out their biological function. Many of the most important molecular processes in the cell such as DNA replication are carried out by large molecular machines that are built from a large number of protein...
