COP9 — Brassica oleracea var. botrytis

Summary

BoCOP9, encoded by the cauliflower gene BOLND125_C08P014370.1_BOLND125_V1 on chromosome 8, belongs to the COP9 signalosome complex subunit 8 (CSN8) family and contains a PCI domain. The product exhibits transcription factor binding, metalloendopeptidase, translation initiation factor, ubiquitin-protein transferase, and DNA-binding transcription factor activities. BoCOP9 is associated with the COP9 signalosome, cullin-RING ligase complex, and ubiquitin ligase complex, and localises to the nucleus, cytoplasm, and cytosol. It is linked to the regulation of photomorphogenesis, floral organ identity specification, endosperm development, and responses to red/far-red light, glucose, sucrose, and maltose. Associations include yield, flowering time, seed and embryo development, root and hypocotyl morphology, anthocyanin content, auxin content and sensitivity, salt and osmotic stress tolerance, high temperature stress response, and UV light sensitivity.
