CC -!- FUNCTION: Element of the brassinosteroid metabolic pathway that CC regulates typhasterol (TY), castasterone (CS) and brassinolide (BL) CC levels (PubMed:17521414). Involved in the control of organ elongation CC (PubMed:17521414, PubMed:23893742). {ECO:0000269|PubMed:17521414, CC ECO:0000269|PubMed:23893742}. CC -!- PATHWAY: Plant hormone biosynthesis; brassinosteroid biosynthesis. CC {ECO:0000269|PubMed:17521414}. CC -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:Q40316}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:17521414}. CC -!- TISSUE SPECIFICITY: Mainly present in cell elongating-containing CC tissues. Strongly expressed in roots and flowers, also observed in CC petioles, stems, leaves and siliques. {ECO:0000269|PubMed:17521414}. CC -!- DEVELOPMENTAL STAGE: First observed after seed germination, mainly in CC the root cap, and in elongation and maturation zones, and, to a lower CC extent, in the apical meristem zone. Later present in roots, with CC higher levels in light conditions than in darkness. Weak levels in CC young flowers. Progressive accumulation in developing siliques, at both CC ends. In rosette leaves, mainly localized in vascular tissues and CC hydathodes. {ECO:0000269|PubMed:17521414}. CC -!- INDUCTION: Down-regulated in the dark. {ECO:0000269|PubMed:17521414}. CC -!- DISRUPTION PHENOTYPE: Abnormal organs elongation leading to long CC inflorescences, leaves and petioles, especially in the light. CC {ECO:0000269|PubMed:17521414, ECO:0000269|PubMed:23893742}. CC -!- MISCELLANEOUS: The ben1-1D (bri1-5 enhanced 1-1dominant) activation- CC tagging mutant suppresses the bri1-5 weak mutant allele of the CC brassinosteroid receptor gene BRI1. {ECO:0000269|PubMed:17521414}. CC -!- SIMILARITY: Belongs to the NAD(P)-dependent epimerase/dehydratase CC family. {ECO:0000305}.
