Journal of Lipid Research, 2009 The mutant Chinese hamster ovary cell line MT58 contains a thermosensitive mutation in CTP:phosphocholine cytidylyltransferase, the regulatory enzyme in the CDP-choline pathway. As a result, MT58 cells have a 50% decrease in their phosphatidylcholine (PC)

Drive, filter, and stick: A protein sorting conspiracy in photoreceptors. [PDF]
, 2019 The sorting of proteins into different functional compartments is a fundamental cellular task. In this issue, Maza et al. (2019. J. Cell Biol https://doi.org/10.1083/jcb.201906024) demonstrate that distinct protein populations are dynamically generated ...

Transport on a Lattice with Dynamical Defects [PDF]
, 2013 Many transport processes in nature take place on substrates, often considered as unidimensional lanes. These unidimensional substrates are typically non-static: affected by a fluctuating environment, they can undergo conformational changes.

TooT-T: discrimination of transport proteins from non-transport proteins [PDF]
BMC Bioinformatics, 2020 Abstract Background Membrane transport proteins (transporters) play an essential role in every living cell by transporting hydrophilic molecules across the hydrophobic membranes. While the sequences of many membrane proteins are known, their structure and function is still not well characterized and understood, owing to the immense effort needed to ...

The Role of Light–Dark Regulation of the Chloroplast ATP Synthase
Frontiers in Plant Science, 2017 The chloroplast ATP synthase catalyzes the light-driven synthesis of ATP and is activated in the light and inactivated in the dark by redox-modulation through the thioredoxin system.

The Tat-dependent protein translocation pathway
Biomolecular Concepts, 2011 The twin-arginine translocation (Tat) pathway is found in bacteria, archaea, and plant chloroplasts, where it is dedicated to the transmembrane transport of fully folded proteins.

Substrate-triggered position switching of TatA and TatB during Tat transport in Escherichia coli [PDF]
Open Biology, 2017 The twin-arginine protein transport (Tat) machinery mediates the translocation of folded proteins across the cytoplasmic membrane of prokaryotes and the thylakoid membrane of plant chloroplasts.

Functional characterization and discovery of modulators of SbMATE, the agronomically important aluminium tolerance transporter from Sorghum bicolor. [PDF]
, 2017 About 50% of the world's arable land is strongly acidic (pH ≤ 5). The low pH solubilizes root-toxic ionic aluminium (Al3+) species from clay minerals, driving the evolution of counteractive adaptations in cultivated crops.

Systemic Long-Distance Signaling and Communication Between Rootstock and Scion in Grafted Vegetables
Frontiers in Plant Science, 2020 Grafting is widely used in fruit, vegetable, and flower propagation to improve biotic and abiotic stress resistance, yield, and quality. At present, the systemic changes caused by grafting, as well as the mechanisms and effects of long-distance signal ...
