HLA-DQ (DQ) is a cell surface receptor protein found on antigen presenting cells. It is an Î±Î² heterodimer of type MHC Class II. The Î± and Î² chains are encoded by the two loci HLA-DQA1 and HLA-DQB1, respectively, which are adjacent to each other on chromosome 6p 21.3. Both Î±-chain and Î²-chain vary greatly. A person often produces two Î±-chain and two Î²-chain variants and thus 4 isoforms of DQ.
