ABA transport and transporters

Trends in Plant Science, 2013
Abscisic acid (ABA) metabolism, perception, and transport form a triptych allowing higher plants to use ABA as a signaling molecule. The molecular bases of ABA metabolism are now well described and, over the past few years, several ABA receptors have been discovered.

ABC transporters in lipid transport

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2000
Since it was found that the P-glycoproteins encoded by the MDR3 (MDR2) gene in humans and the Mdr2 gene in mice are primarily phosphatidylcholine translocators, there has been increasing interest in the possibility that other ATP binding cassette (ABC) transporters are involved in lipid transport.

To transport or not to transport

Science, 2019
Structural Biology Therapeutic drug delivery into cells is complicated by membrane proteins like ABCB1 (also termed P-glycoprotein) that shuttle diverse compounds out of cells. Alam et al. determined high-resolution cryo–electron microscopy structures of ABCB1 bound either to a substrate, the cancer drug Taxol, or to the ABCB1 inhibitor zosuquidar. The

The intracellular transport of transporters: membrane trafficking of mineral transporters

Current Opinion in Plant Biology, 2009
For mineral nutrients to be used by plants, they must be taken up from soil solutions into root cells and then transported to shoots. Mineral nutrient transporters play a central role in this process, and their expression and accumulation are known to be strictly regulated in response to change in nutrient conditions.

Of Transport and Transportation

The Eighteenth Century, 2016
This essay shows how the institution of punishment by criminal transportation was entangled with the aesthetics of sublime transport introduced into English literary parlance by Boileau’s 1674 translation of Longinus’ Peri Hypsous, which would later become, in English, On the Sublime.

Thyroid Hormone Transport and Transporters

2018
Thyroid hormones orchestrate developmental processes and are among the most important regulators of energy metabolism. Thyroid hormone actions are mostly, but not exclusively, mediated by nuclear hormone receptors. As amino acid derivatives, thyroid hormones need plasma membrane transporters in order to reach their nuclear receptors.
