Homo sapiens

Also known as XPE; DDBB; UV-DDB2

Gene ID: 1643 | Gene type: protein coding

About DDB2

Cytogenetic location: 11p11.2 Genomic coordinates (GRCh38): 11:47,214,454-47,239,217 (from NCBI)

This gene has 16 transcripts (splice variants), 190 orthologues and is associated with 60 phenotypes. Ubiquitous expression in skin (RPKM 32.0), esophagus (RPKM 13.6) and 24 other tissues.

Summary

This gene encodes a protein that is necessary for the repair of ultraviolet light-damaged DNA. This protein is the smaller subunit of a heterodimeric protein complex that participates in nucleotide excision repair, and this complex mediates the ubiquitylation of histones H3 and H4, which facilitates the cellular response to DNA damage. This subunit appears to be required for DNA binding. Mutations in this gene cause xeroderma pigmentosum complementation group E, a recessive disease that is characterized by an increased sensitivity to UV LIGHT and a high predisposition for skin Cancer development, in some cases accompanied by neurological abnormalities. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]
