function:May be involved in ubiquitination and subsequent proteasomal degradation of target proteins. Component of the DDD-E2 complexes which may provide a platform for interaction with CUL4A and WD repeat proteins.,similarity:Belongs to the DDA1 family.,subunit:Part of the DDD core complex containing DET1, DDA1 and DDB1. The DDD core complex recruits a specific UBE2E enzyme, such as UBE2E1, UBE2E2 UBE2E3, to form specific DDD-E2 complexes.,
