COP1 — Nicotiana attenuata

Summary

A4A49_29644 (COP1) in coyote tobacco (Nicotiana attenuata) encodes a protein with ubiquitin ligase activity, structural molecule activity, histone binding, identical protein binding, and zinc binding, containing COP1, WD40 repeat, and RING zinc finger domains. This gene is associated with photomorphogenesis, red and far-red light phototransduction, photoprotection, regulation of seed maturation, nicotine anabolism, protein ubiquitination, proteolysis via the proteasomal pathway, nuclear export, intracellular protein transport, ER-to-Golgi and intra-Golgi transport, DNA replication and repair, chromatin modeling, and virus-induced PTGS. It localizes to the nucleus, cytoplasm, Golgi membrane, and coatomer. Associations with chlorophyll content and plant height have also been noted. Related genes in other species link the family to chromatin regulation and vesicle-mediated transport.
