Lipid bilayer composition influences small multidrug transporters [PDF]

open access: yes, 2008
Background: Membrane proteins are influenced by their surrounding lipids. We investigate the effect of bilayer composition on the membrane transport activity of two members of the small multidrug resistance family; the Escherichia coli transporter, EmrE

New putative chloroplast vesicle transport components and cargo proteins revealed using a bioinformatics approach: an Arabidopsis model. [PDF]

open access: yesPLoS ONE, 2013
Proteins and lipids are known to be transported to targeted cytosolic compartments in vesicles. A similar system in chloroplasts is suggested to transfer lipids from the inner envelope to the thylakoids. However, little is known about both possible cargo

Transport of Cytoplasmically Synthesized Proteins into the Mitochondria in a Cell Free System from Neurospora crassa [PDF]

open access: yes, 1977
Synthesis and transport of mitochondrial proteins were followed in a cell-free homogenate of Neurospora crassa in which mitochondrial translation was inhibited. Proteins synthesized on cytoplasmic ribosomes are transferred into the mitochondrial fraction.

Occurrence and potential mechanism of holin-mediated non-lytic protein translocation in bacteria

open access: yesMicrobial Cell, 2022
Holins are generally believed to generate large membrane lesions that permit the passage of endolysins across the cytoplasmic membrane of prokaryotes, ultimately resulting in cell wall degradation and cell lysis. However, there are more and more examples

Extragenic Suppression analysis of TS mutations using Sec61p [PDF]

open access: yes, 2007
During synthesis, secretory and membrane proteins are cotranslationally translocated into the lumen of the endoplasmic reticulum through an aqueous gated channel.

Active Nuclear Import of Membrane Proteins Revisited

open access: yesCells, 2015
It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). For the Saccharomyces cerevisiae proteins Src1/Heh1 and Heh2, a transport mechanism was proposed where ...

Energetic constraints on filament mediated cell polarization [PDF]

open access: yes, 2021
Cell polarization underlies many cellular processes, such as differentiation, migration, and budding. Many living cells, such as budding yeast and fission yeast, use cytoskeletal structures to actively transport proteins to one location on the membrane and create a high density spot of membrane-bound proteins.

Translocation and insertion of precursor proteins into isolated outer membranes of mitochondria [PDF]

open access: yes, 1993
Nuclear-encoded proteins destined for mitochondria must cross the outer or both outer and inner membranes to reach their final sub- mitochondrial locations. While the inner membrane can translocate preproteins by itself, it is not known whether the outer

Electron transport and light-harvesting switches in cyanobacteria

open access: yesFrontiers in Plant Science, 2014
Cyanobacteria possess multiple mechanisms for regulating the pathways of photosynthetic and respiratory electron transport. Electron transport may be regulated indirectly by controlling the transfer of excitation energy from the light-harvesting ...

The second intracellular loop of the yeast Trk1 potassium transporter is involved in regulation of activity, and interaction with 14–3-3 proteins

open access: yesComputational and Structural Biotechnology Journal, 2023
Potassium is an essential intracellular ion, and a sufficient intracellular concentration of it is crucial for many processes; therefore it is fundamental for cells to precisely regulate K+ uptake and efflux through the plasma membrane.
