COP1 — Nicotiana attenuata

Summary

A4A49_12414 (COP1) on chromosome 2 of coyote tobacco (Nicotiana attenuata) encodes a protein containing WD40 repeats and domains characteristic of the COP1 family. The product exhibits ubiquitin ligase activity, histone binding, transcription corepressor binding, structural molecule activity, identical protein binding, and zinc binding. It is associated with photomorphogenesis, red and far-red light phototransduction, photoprotection, regulation of seed maturation, nicotine anabolism, nuclear export, intracellular protein transport, ER-to-Golgi and intra-Golgi transport, chromatin modeling, DNA recombination and replication, proteasomal pathway, protein ubiquitination, and proteolysis. The protein localises to the nucleus, cytoplasm, Golgi membrane, coatomer, chromatin silencing complex, and DP/Rb/MuvB complex. This gene is also linked to chlorophyll content and plant height. Related genes in other species connect the family to chromatin regulation and vesicle transport.
