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]

Gene Networks

Gene regulatory network (GRN) of the gene in two interaction steps distance for the selected cell types. The network depth can be varied by updating the number in the box of Network Settings. The GRN is based on C3NET algorithm [1]. Each links are the highest association scores for one of the genes of gene pairs. The numbers near the checked boxes refer to the numbers of links contributed by each of the cell types. One can uncheck and remove the links of any of the cell types from the network. The network topology is dynamic and can be re-arranged by pulling a node with a mouse. The solid and dashed lines refer to positive and negative correlations, respectively. Right clicking a node will bring up a menu with additional options. The arrows show the most likely direction of regulation between gene pairs.
