NCBI Protein Information
damaged DNA binding protein 1A
NCBI Summary
Structurally similar to damaged DNA binding proteins. DDB1a is part of a 350 KDa nuclear localized DET1 protein complex. This complex may physically interact with histone tails and while bound to chromatin- repress transcription of genes involved in photomorphogenesis. DDB1a is shown to be RUB-modified.

UniProt Comments
Component of light signal transduction machinery. Involved in repression of photomorphogenesis in darkness by participating in the CDD complex, a complex probably required to regulate the activity of ubiquitin conjugating enzymes (E2s). Repression of photomorphogenesis is probably mediated by ubiquitination and subsequent degradation of photomorphogenesis-promoting factors such as HY5, HYH and LAF1. Plays a role in DNA repair by forming with DDB2 the UV-damaged DNA-binding protein complex (UV-DDB). Component of the CUL4-RBX1-DDB1-PRL1 E3 ubiquitin-protein ligase complex.
