The FKBP42, TWISTED DWARF1, prioritizes auxin over brassinosteroidtransport by peptidyl-prolyl cis-trans isomerization of ABCB1
The ATP-binding cassette (ABC) transporter ABCB1 transports both auxins and the brassinosteroid brassinolide (BL).
The ATP-binding cassette (ABC) transporter ABCB1 transports both auxins and the brassinosteroid brassinolide (BL). ABCB1-mediated auxin (IAA) transport depends on interaction with the FKBP42 protein TWISTED DWARF1 (TWD1), yet the mechanism underlying substrate selectivity…
