Compartmentalization and Transport in Synthetic Vesicles

Frontiers in Bioengineering and Biotechnology, 2016
Nano-scale vesicles have become a popular tool in life sciences. Besides liposomes that are generated from phospholipids of natural origin, polymersomes fabricated of synthetic block copolymers enjoy increasing popularity, as they represent more ...

Structural and functional characterization of the integral membrane proteins CitS and CCR5 by electron microscopy [PDF]

, 2013
Secondary transport proteins are integral membrane proteins found in every cell. They facilitate the transport of versatile substrates (e.g. nutrients, ions and drugs) across the hydrophobic membrane barrier.

Multiple determinants direct the orientation of signal-anchor proteins : the topogenic role of the hydrophobic signal domain [PDF]

, 1997
The orientation of signal-anchor proteins in the endoplasmic reticulum membrane is largely determined by the charged residues flanking the apolar, membrane-spanning domain and is influenced by the folding properties of the NH2-terminal sequence. However,

Outer membrane biogenesis in Helicobacter pylori: A deviation from the paradigm

Frontiers in Cellular and Infection Microbiology, 2012
The bacterial pathogen Helicobacter pylori is capable of colonizing the gastric mucosa of the human stomach using a variety of factors associated with or secreted from its outer membrane (OM).

Nucleoplasmic signals promote directed transmembrane protein import simultaneously via multiple channels of nuclear pores

Nature Communications, 2020
The contribution of central and peripheral channels of nuclear pores to transport of transmembrane proteins is unclear. Here the authors show that most inner nuclear membrane proteins use only peripheral channels, but some extend nuclear localization ...

Nocodazole, a microtubule-active drug, interferes with apical protein delivery in cultured intestinal epithelial cells (Caco-2) [PDF]

, 1989
The polarized delivery of membrane proteins to the cell surface and the initial secretion of lysosomal proteins into the culture medium were studied in the polarized human intestinal adenocarcinoma cell line Caco-2 in the presence or absence of the ...

Types of Membrane Transporters and the Mechanisms of Interaction between Them and Reactive Oxygen Species in Plants

Antioxidants
Membrane transporters are proteins that mediate the entry and exit of substances through the plasma membrane and organellar membranes and are capable of recognizing and binding to specific substances, thereby facilitating substance transport.

An Optimized Screen Reduces the Number of GA Transporters and Provides Insights Into Nitrate Transporter 1/Peptide Transporter Family Substrate Determinants

Frontiers in Plant Science, 2019
Based on recent in vitro data, a relatively large number of the plant nitrate transporter 1/peptide transporter family (NPF) proteins have been suggested to function as gibberellic acid (GA) transporters.
