The FKBP42, TWISTED DWARF1, prioritizes auxin over brassinosteroid transport by peptidyl-prolyl cis-trans isomerization of ABCB1

The paper shows TWD1 enhances IAA transport by isomerizing the E1007-P1008 bond in ABCB1, while not affecting BL transport, revealing a mechanism that prioritizes auxin over brassinosteroid transport.

A key residue of the extracellular gate provides quality control contributing to ABCG substrate specificity

The paper shows that mutation of L704 in ABCG36 affects substrate specificity by altering transport of IBA and CLX, with molecular dynamics supporting a quality control role.

A CELL BIOLOGY STUDY REVEALS NEW INSIGHTS INTO THE TRANSPORT MECHANISMS OF OOMYCETE EFFECTORS

This study identifies the RXLR-EER motif as critical for directing oomycete effectors to the haustorial neck for host cell entry.

TWISTED DWARF1 regulates Arabidopsis stamen development by differential activation of ABCB-mediated auxin transport

The paper identifies TWD1 as a master regulator of Arabidopsis stamen development by modulating ABCB-mediated auxin transport, with distinct roles for ABCB1 and ABCB19 in different developmental stages.

AlphaFold2 transmembrane protein structure prediction shines

This study evaluates AlphaFold2's performance in predicting transmembrane protein structures and finds it highly accurate even for TM proteins.
