Seems to act as transcriptional activator. Formation of heterodimers with Aux/IAA proteins may alter their ability to modulate early auxin response genes expression. Regulates both stamen and gynoecium maturation. Promotes jasmonic acid production. Partially redundant with ARF8. (935 aa) |
| | NPR5 | Regulatory protein NPR5; May act as a substrate-specific adapter of an E3 ubiquitin- protein ligase complex (CUL3-RBX1-BTB) which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). Acts redundantly with BOP2. BOP1/2 promote leaf and floral meristem fate and determinacy in a pathway targeting AP1 and AGL24. BOP1/2 act as transcriptional co-regulators through direct interaction with TGA factors, including PAN, a direct regulator of AP1. Controls lateral organ fate through positive regulation of adaxial-abaxial polarity genes ATHB-14/PHB [...] (491 aa) |
