SF OBP3 was able to significantly stimulate the binding of OBF4 protein to the GST6 promoter [1];
SF nuclear localized [2];
XX
CP strong in roots; weak in flowers, leaves and stems [1]; expression levels increased following treatment with auxin, salicylic acid (SA) or cycloheximide [1]; apex, cotyledons root apex of dark-grown seedlings [2]; in light-grown seedlings: shoot apex, vascular tissue of the cotyledons, hypocotyls and roots [2] [1] [2].
XX
FF overexpressing OBP3 plants showed a severe growth defect with altered root development and yellowish leaves [1];
FF overexpression results in suppression of the long-hypocotyl phenotype of phyB-4 [2];
FF tissue-specific localization is regulated by light [2];
FF hypocotyls of partial-loss-of-function lines (OBP3-RNAi) are less responsive to red light in a phyB-dependent manner [2];
FF negative regulator of cry1-mediated cotyledon expansion in response to blue light [2];
