Summary
HLA-DRB5 belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DRA) and a beta (DRB) chain, both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. 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. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogues DRB3, DRB4 and DRB5. The presence of DRB5 is linked with allelic variants of DRB1, otherwise it is omitted. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9. [provided by RefSeq, Jul 2008]

Differential expression
Differential gene expression across cell types as calculated by the DESeq package (version 1.6.3). Cells are sorted based on median gene expression from highest to lowest. Squares in the upper diagonal matrix indicate results from pair-wise comparisons of two cell types on the x- and y-axis. Changing the tab on top will switch from log2 fold change to P values, and mousing over the squares will display those values. Adjusting the threshold slider will change the color of the square to indicate if it is above or below the threshold.

DICE QTLs
Discovery of genetic variants directly associated with the gene expression level (SNP located within +/- 1 Mb of the TSS); 'expression quantitative trait loci' (eQTL). Hover over the table headers for a description of several of the fields.

RNA expression levels (in reads per million) averaged across samples are shown for each cell type, along with the Gencode annotations. Controls allow you to zoom in/out, move to a different region of the genome, change scales, or add/remove tracks. Future versions will also display SNPs/eQTLs as separate tracks.
