Webone of the most polymorphic gene systems known. The human genome contains hundreds of alleles for these loci, whereby each of the alleles encode MHC/HLA molecules that differ in their peptide binding groove, affording each of them a unique peptide binding motif and thus peptide presentation property. WebIn humans, the MHC is a cluster of genes located on chromosome 6 which code for MHC proteins also called Human Leukocyte Antigen (HLA). MHC proteins are a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules which in turn determines histocompatibility. The main function of MHC molecules is to bind ...
