About HLA-DRA

Cytogenetic location: 6p21.32 Genomic coordinates (GRCh38): 6:32,439,887-32,445,046 (from NCBI)

This gene has 2 transcripts (splice variants), 1 gene allele, 148 orthologues, 13 paralogues and is associated with 1 phenotype. Broad expression in lymph node (RPKM 921.6), lung (RPKM 809.6) and 24 other tissues.

Summary

HLA-DRA is one of the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha and a beta chain, both anchored in the membrane. This molecule is expressed on the surface of various antigen presenting cells such as B lymphocytes, dendritic cells, and monocytes/macrophages, and plays a central role in the immune system and response by presenting Peptides derived from extracellular proteins, in particular, pathogen-derived Peptides to T cells. The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and the cytoplasmic tail. DRA does not have polymorphisms in the peptide binding part and acts as the sole alpha chain for DRB1, DRB3, DRB4 and DRB5. [provided by RefSeq, Aug 2020]
