Protein function
Encodes a regulator of the activity of E2 ubiquitine conjugating enzymes.
Phenotype
Single mutant: det1 single mutant is early flowering under SD conditions only. ( Conflicting results under LD conditions. The phenotype is anyway much stronger under SD conditions.)
[Kang et al., 2015][Pepper et al., 1997] Function: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). Involved in repression of deetiolation in the developing seedling. Repression of photomorphogenesis is probably mediated by ubiquitination and subsequent degradation of photomorphogenesis-promoting factors such as HY5, HYH and LAF1. Involved in the repression of blue light responsive promoter in chloroplasts. May be required to stabilize the CDD complex. Its association with histone tail suggests a role in remodeling of chromatin.
