This class II molecule is a heterodimer consisting of an alpha (DMA) and a beta chain (DMB), both anchored in the membrane. It is located in intracellular vesicles. DM plays a central role in the peptide loading of MHC class II molecules by helping to release the CLIP molecule from the peptide binding site. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and the cytoplasmic tail.[6]References[edit]^ a b c ENSG00000243719, ENSG00000239463, ENSG00000204257, ENSG00000242361, ENSG00000241394, ENSG00000243189, ENSG00000242685 GRCh38: Ensembl release 89: ENSG00000243215, ENSG00000243719, ENSG00000239463, ENSG00000204257, ENSG00000242361, ENSG00000241394, ENSG00000243189, ENSG00000242685 – Ensembl, May 2017^ a b c GRCm38: Ensembl release 89: ENSMUSG00000037649 – Ensembl, May 2017^ “Human PubMed Reference:”.
