Naturally Occurring N-Terminal Fragments of Bovine Milk Osteopontin Are Transported across Models of the Intestinal Barrier

open access: yesBiomedicines, 2023
Osteopontin (OPN) is a bioactive integrin-binding protein found in high concentrations in milk, where it is present both as a full-length protein and as several N-terminally derived fragments.

An extracellular vesicle targeting ligand that binds to Arc proteins and facilitates Arc transport in vivo

open access: yeseLife, 2023
Communication between distant cells can be mediated by extracellular vesicles (EVs) that deliver proteins and RNAs to recipient cells. Little is known about how EVs are targeted to specific cell types.

Haploid male germ cells-the Grand Central Station of protein transport.

open access: yesHuman Reproduction Update, 2020
BACKGROUND The precise movement of proteins and vesicles is an essential ability for all eukaryotic cells. Nowhere is this more evident than during the remarkable transformation that occurs in spermiogenesis-the transformation of haploid round spermatids

The role of microtubules in secretory protein transport

open access: yesJournal of Cell Science, 2020
Microtubules are part of the dynamic cytoskeleton network and composed of tubulin dimers. They are the main tracks used in cells to organize organelle positioning and trafficking of cargos. In this Review, we compile recent findings on the involvement of

Analysis of Dot/Icm Type IVB Secretion System Subassemblies by Cryoelectron Tomography Reveals Conformational Changes Induced by DotB Binding

open access: yesmBio, 2020
Type IV secretion systems (T4SSs) are sophisticated nanomachines used by many bacterial pathogens to translocate protein and DNA substrates across a host cell membrane.

Towards a molecular mechanism underlying mitochondrial protein import through the TOM and TIM23 complexes

open access: yeseLife, 2022
Nearly all mitochondrial proteins need to be targeted for import from the cytosol. For the majority, the first port of call is the translocase of the outer membrane (TOM complex), followed by a procession of alternative molecular machines, conducting ...

Protein transport into mitochondria [PDF]

open access: yesCurrent Opinion in Microbiology, 2000
Mitochondria are made up of two membrane systems that subdivide this organelle into two aqueous subcompartments: the matrix, which is enclosed by the inner membrane, and the intermembrane space, which is located between the inner and the outer membrane.

Quantum tunneling of three-spine solitons through excentric barriers [PDF]

open access: yesPhysics Letters A 2022; 448: 128319, 2022
Macromolecular protein complexes catalyze essential physiological processes that sustain life. Various interactions between protein subunits could increase the effective mass of certain peptide groups, thereby compartmentalizing protein $\alpha$-helices.
