HLA-C

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 many HLA-C alleles that are Class-I MHC receptors. HLA-C, localized proximal to the HLA-B locus, is located on the distal end of the HLA region. Most HLA-C: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 with:

gollark: That's not "encryption" any more than rot13 is.
gollark: * base64
gollark: We are an intelligent species. Mostly. We can try and actively manage population and such.
gollark: > You breed maybe once or twiceActually, I may just not have children, it seems inconvenient and annoying.
gollark: My inability to visually imagine things is really helpful on the internet, honestly!
