HLA-DMB - major histocompatibility complex, class II, DM beta Gene
Also Known as RING7; D6S221E
Species: Homo sapiens
About HLA-DMB
This gene has 6 transcripts (splice variants), 1 gene allele, 149 orthologues and 13 paralogues. Broad expression in lymph node (RPKM 104.0), spleen (RPKM 76.5) and 24 other tissues.
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 peptide loading of MHC class II molecules by helping to release the CLIP (class II-associated invariant chain peptide) molecule from the peptide binding site. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail.
