DNA damage-binding protein 2 is a protein that in humans is encoded by the DDB2 gene.[1][2]

DDB2 is the smaller subunit of a heterodimeric protein implicated in the etiology of xeroderma pigmentosum group E. This subunit appears to be required for DNA binding.[3]

Interactions[edit]

DDB2 has been shown to interact with CUL4A,[4] CUL4B[4] and DDB1.[4][5][6] Also, some researches about DDB2 show a relationship between DDB2 and PARP1.PARP1 as a novel DDB2-associated factor,which may help to recruitment a chromatin-remodeling enzyme,named ALC1.[7]
