IPK | Isopentenyl phosphate kinase; Catalyzes the formation of isopentenyl diphosphate (IPP), the universal five-carbon isoprenoid building block of all natural isoprenoids. Acts in parallel with the mevalonate (MVA) pathway and plays an important role in regulating the formation of both MVA and methylerythritol phosphate (MEP) pathway- derived terpenoid compounds by controlling the ratio of isopentenyl phosphate (IP) and dimethylallyl phosphate (DMAP) to isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Controls the levels of IP and DMAP that are competitive inhibitors of [...] (332 aa) | ||||
BZR1 | Protein BRASSINAZOLE-RESISTANT 1; Transcriptional repressor that binds to the brassinosteroid (BR) response element (BRRE) 5'-CGTG(T/C)G-3' in gene promoter. Regulates positively the brassinosteroid-signaling pathway. Mediates downstream growth responses and negative feedback regulation of brassinosteroid biosynthesis. Promotes growth. Modulates ovule initiation and development by monitoring the expression of genes related to ovule development (e.g. HLL, ANT, and AP2). (336 aa) | ||||
BIM1 | Transcription factor BIM1; Positive brassinosteroid-signaling protein. Transcription factor that bind specifically to the DNA sequence 5'-CANNTG-3'(E box). Can bind individually to the promoter as a homodimer or synergistically as a heterodimer with BZR2/BES1. Does not itself activate transcription but enhances BZR2/BES1-mediated target gene activation. (529 aa) | ||||
BZR2 | Protein BRASSINAZOLE-RESISTANT 2; Positive regulator of brassinosteroid (BR) signaling. Transcription factor that activates target gene expression by binding specifically to the DNA sequence 5'-CANNTG-3'(E box) through its N- terminal domain. Can bind individually to the promoter as a homodimer or synergistically as a heterodimer with BIM1, BIM2 or BIM3. The C- terminal domain is probably involved in transcriptional activation. Recruits the transcription elongation factor IWS1 to control BR- regulated gene expression. Forms a trimeric complex with IWS1 and ASHH2/SDG8 to regulate BR-reg [...] (335 aa) |
