Gene Gene information from NCBI Gene database.
Entrez ID 1643
Gene name Damage specific DNA binding protein 2
Gene symbol DDB2
Synonyms (NCBI Gene)
DDBBUV-DDB2XPE
Chromosome 11
Chromosome location 11p11.2
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 ubiquityla
