DET1- and DDB1-associated protein 1, N-terminal (IPR018276)

Short name: DDA1_N

Overlapping homologous superfamilies


Domain relationships



This entry represents the N-terminal domain of DDA1 (DET1- and DDB1-associated protein 1) ubiquitin ligase, which binds strongly with Det1 (De-etiolated 1) and DDB1 (Damaged DNA binding protein 1 associated 1). Together DDA1, DDB1 and Det1 form the DDD core complex, which recruits a specific UBE2E enzyme to form specific DDD-E2 complexes [PMID: 17452440]. Component of the DDD-E2 complexes which may provide a platform for interaction with cul4a and WD repeat proteins. These proteins may be involved in ubiquitination and subsequent proteasomal degradation of target proteins.
