Summary
Introduction
The MHC is localized on the short arm of chromosome 6 in band 21.3. It extends over 4 Mb of DNA, which have been intensively studied for several decades. Detailed physical maps have been derived and the entire complex has been cloned in cosmid and yeast artificial chromosome (YAC) vectors. About 80 genes have been identified so far, which include the genes encoding the class I or classical transplantation antigens, the class II immune response genes, the class III genes originally defined by complement components and a number of novel genes involved in antigen processing or of unknown function (Trowsdale, Ragoussis & Campbell, 1991). It is intriguing that so many genes involved in immune responses are closely linked to each other in the genome. The class I and class II sequences have been maintained together through evolution and can be found on the same chromosome in species like chicken, mouse and humans. The organization and functional relationships between MHC genes will be presented in this chapter along with a description of MHC transcripts.
The class I region
The human class I region
The class I region is 2 Mb in length and contains the class I multigene family comprising about 20 non-allelic DNA sequences (Fig. 2.1).
