GUS-NC80 fusion protein
Construct PatternThe GUS-NC80 fusion protein is a transgenic plant construct in which β-glucuronidase is fused to the 80-residue NC80 motif from Arabidopsis CRY2. In the cited study, this fusion was constitutively active despite being unphosphorylated, supporting that NC80 is sufficient to confer CRY2 physiological function when derepressed.
