A twist in the ABC : regulation of ABC transporter trafficking and transport by FK506‐binding proteins

Geisler, Markus ; Hegedűs, Tamás

In: FEBS Letters, 2020, vol. 594, no. 23, p. 3986-4000

Post-transcriptional regulation of ATP-binding cassette (ABC) proteins has been so far shown to encompass protein phosphorylation, maturation, and ubiquitination. Yet, recent accumulating evidence implicates FK506-binding proteins (FKBPs), a type of peptidylprolyl cis–trans isomerase (PPIase) proteins, in ABC transporter regulation. In this perspective article, we summarize current knowledge on...

Auxin-transporting ABC transporters are defined by a conserved D/E-P motif regulated by a prolylisomerase

Hao, Pengchao ; Xia, Jian ; Liu, Jie ; Donato, Martin Di ; Pakula, Konrad ; Bailly, Aurélien ; Jasinski, Michal ; Geisler, Markus

The plant hormone auxin must be transported throughout plants in a cell-to-cell manner to affect its various physiological functions. ABCB transporters are critical for this polar auxin distribution, but the regulatory mechanisms controlling their function is not fully understood. The auxin transport activity of ABCB1 was suggested to be regulated by a physical interaction with FKBP42/Twisted...

TORC1 specifically inhibits microautophagy through ESCRT-0

Hatakeyama, Riko ; Virgilio, Claudio De

In: Current Genetics, 2019, vol. 65, no. 5, p. 1243–1249

Nutrient starvation induces the degradation of specific plasma membrane proteins through the multivesicular body (MVB) sorting pathway and of vacuolar membrane proteins through microautophagy. Both of these processes require the gateway protein Vps27, which recognizes ubiquitinated cargo proteins at phosphatidylinositol 3-phosphate-rich membranes as part of a heterodimeric complex coined...

Anion-induced structural diversity of Zn and Cd coordination polymers based on bis-9,10-(pyridine-4-yl)-anthracene, their luminescent properties, and highly efficient sensing of nitro derivatives and herbicides

Vasylevskyi, Serhii I. ; Bassani, Dario M. ; Fromm, Katharina M.

In: Inorganic Chemistry, 2019, vol. 58, no. 9, p. 5646–5653

Luminescent coordination polymers (CPs) of Zn2+ or Cd2+ and bis-9,10-(pyridine-4- yl)-anthracene (BA) show different 1D and 2D topologies depending on the anion used in the precursor. Compounds {[Zn(μ2-BA)(MeOH)2(p-Tos)2]}n (1) and {[Zn(μ2- BA)(MeOH)2(CF3CO2)2]}n (2) form linear structures and {BA@[Zn(μ2-BA) (MeOH)2(H2O)2](CF3SO3)2}n (3) featuring intercalation of uncoordinated BA molecules...

A substrate of the ABC transporter PEN3 stimulates bacterial flagellin (flg22)-induced callose deposition in Arabidopsis thaliana

Matern, Andreas ; Böttcher, Christoph ; Eschen-Lippold, Lennart ; Westermann, Bernhard ; Smolka, Ulrike ; Döll, Stefanie ; Trempel, Fabian ; Aryal, Bibek ; Scheel, Dierk ; Geisler, Markus ; Rosahl, Sabine

In: Journal of Biological Chemistry, 2019, vol. 294, no. 17, p. 6857–6870

Nonhost resistance of Arabidopsis thaliana against Phytophthora infestans, a filamentous eukaryotic microbe and the causal agent of potato late blight, is based on a multilayered defense system. Arabidopsis thaliana controls pathogen entry through the penetration-resistance genes PEN2 and PEN3, encoding an atypical myrosinase and an ABC transporter, respectively, required for synthesis and...
