Presynaptic Precursor Vesicles—Cargo, Biogenesis, and Kinesin-Based Transport across Species
Cells, 2023 The faithful formation and, consequently, function of a synapse requires continuous and tightly controlled delivery of synaptic material. At the presynapse, a variety of proteins with unequal molecular properties are indispensable to compose and control ...

Evolution of the Membrane Transport Protein Domain
International Journal of Molecular Sciences, 2022 Membrane transport proteins are widely present in all living organisms, however, their function, transported substrate, and mechanism of action are unknown. Here we use diverse bioinformatics tools to investigate the evolution of MTPs, analyse domain organisation and loop topology, and study the comparative alignment of modelled 3D structures.

Regulation of Plasma Membrane Sterol Homeostasis by Nonvesicular Lipid Transport
Contact, 2021 Sterol contributes to the structural integrity of cellular membranes and plays an important role in the regulation of cell signaling in eukaryotes. It is either produced in the endoplasmic reticulum or taken up from the extracellular environment. In most

Protein transport in organelles: Protein transport into and across the thylakoid membrane [PDF]
The FEBS Journal, 2009 The chloroplast thylakoid is the most abundant membrane system in nature, and is responsible for the critical processes of light capture, electron transport and photophosphorylation. Most of the resident proteins are imported from the cytosol and then transported into or across the thylakoid membrane. This minireview describes the multitude of pathways

Transport Phenomena in Fluid Films with Curvature Elasticity [PDF]
J. Fluid Mech. 905 (2020) A8, 2020 Cellular membranes are elastic lipid bilayers that contain a variety of proteins, including ion channels, receptors, and scaffolding proteins. These proteins are known to diffuse in the plane of the membrane and to influence the bending of the membrane.

Reaction-Diffusion Waves Coupled with Membrane Curvature [PDF]
Soft Matter,17, 6589-6596 (2021), 2021 The reaction-diffusion waves of proteins are known to be involved in fundamental cellular functions, such as cell migration, cell division, and vesicular transportation. In some of these phenomena, pattern formation on the membranes is induced by the coupling between membrane deformation and the reaction-diffusion system through curvature-inducing ...
