This study reveals that MYC2 and GBF1 colocalize and physically interact in the nucleus. This interaction requires the N-terminal domain of each protein.
GBF1 is a transcriptional repressor of the AtCathB3 gene and affects germination kinetics of A. thaliana seeds. As AtCathB3 is also expressed during post-germination in cotyledons a role for the AtCathB3-like protease in reserve mobilization is inferred.
In Arabidopsis GBF1-related exchange factors for the ARF GTPases (ARF GEFs) GNOM and GNL2 play essential roles in polar tip growth of root hairs and pollen respectively.
GBF1 a transcription factor of blue light signaling in Arabidopsis is degraded in the dark by a proteasome-mediated pathway independent of COP1 and SPA1
