AT4G10180 — Arabidopsis thaliana

Summary

AT4G10180 (DET1, DE-ETIOLATED 1) in Arabidopsis thaliana encodes a de-etiolated protein 1 family member with multiple molecular functions including phosphatidylethanolamine binding, phytochrome binding, blue light photoreceptor activity, FAD binding, DNA-binding transcription factor activity, and ubiquitin ligase activity. DET1 is associated with phototransduction, dark adaptation, downregulation of circadian rhythm, protein monoubiquitination, and positive regulation of ROS metabolic process. It localizes to nuclear bodies, the Cul4-RING E3 ubiquitin ligase complex, and the SCF complex. The gene is linked to salt stress resistance, and associations include stem number, branch number, fruit number, flower number, seedling height, drought recovery, leaf area, harvest index, photoperiod sensitivity, blue light sensitivity, and pigment production. Related genes in other species link the DET1 family to fruit morphology, carotene and lycopene content, and photosynthetic ability.
