HLA-DMB (major histocompatibility complex, class II, DM beta)

Gene

• Entrez ID: 3109
• Gene name: Major histocompatibility complex, class II, DM beta
• Gene symbol: HLA-DMB
• Synonyms (NCBI Gene): D6S221E, RING7
• Chromosome: 6
• Chromosome location: 6p21.32
• Summary: HLA-DMB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DMA) and a beta (DMB) chain, both anchored in the membrane. It is located in intracellular vesicles. DM plays a central role in the
