HLA-DMA - major histocompatibility complex, class II, DM alpha Gene
Also Known as DMA; HLADM; RING6; D6S222E
Species: Homo sapiens
About HLA-DMA
This gene has 9 transcripts (splice variants), 1 gene allele, 111 orthologues and 13 paralogues. Broad expression in lymph node (RPKM 124.3), lung (RPKM 102.4) and 24 other tissues.
Summary
HLA-DMA belongs to the HLA class II alpha chain paralogues. 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. [provided by RefSeq, Jul 2008]
