PAT — Nicotiana attenuata

Summary

A4A49_60656 (PAT, also known as RUB2) on chromosome 11 of coyote tobacco encodes a Nedd8-like ubiquitin-like modifier with ubiquitin-like modifier activating enzyme activity and protein tag function. It is associated with protein neddylation, SCF complex assembly, protein ubiquitination, modification-dependent proteolysis, and cellular auxin homeostasis. The gene is linked to jasmonic acid signaling and response, ethylene anabolism, response to cytokinin and red/far-red light, regulation of circadian rhythm, leaf and flower development, endosperm development, and phloem or xylem histogenesis. Associations include biomass yield, flowering time, shoot axis branching, leaf vein and trichome morphology, lateral root length, phototropism, herbicide sensitivity, disease tolerance, and gibberellic acid sensitivity. The protein localizes to CRL and ubiquitin ligase complexes, cytosol, ER, and plasmalemma.
