Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation

open access: yesFEBS Letters, EarlyView.
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.

Gα16, a G Protein α Subunit Specifically Expressed in Hematopoietic Cells [PDF]

open access: yes, 1991
Signal-transduction pathways mediated by guanine nucleotide-binding regulatory proteins (G proteins) determine many of the responses of hematopoietic cells.

Single-phase feeding and compensatory growth in growing and finishing pigs (OK-Net Ecofeed Practice Abstract) [PDF]

open access: yes, 2020
• Limit the supply of essential amino acids during early growth and utilise the pigs’ capacity to fully compensate for the restriction by increased protein retention and faster growth during later growth phases.

Synthetic phospholipid vesicles containing a purified viral antigen and cell membrane proteins stimulate the development of cytotoxic T lymphocytes [PDF]

open access: yes, 1979
Synthetic phospholipid vesicles (liposomes) containing the purified glycoprotein (G) of vesicular stomatitis virus (VSV) and solubilized membrane proteins from cells of the appropriate H-2 haplotype elicited H-2-restricted cytotoxic T lymphocytes (CTL ...

Targeting G protein-coupled receptor signaling at the G protein level with a selective nanobody inhibitor

open access: yesNature Communications, 2018
G protein-coupled receptors (GPCRs) activate and dissociate the G protein heterotrimer into Gα-GTP and Gβγ dimer, which facilitate distinct signalling events.

G‐protein coupled receptor kinases as modulators of G‐protein signalling

open access: yesThe Journal of Physiology, 1999
G‐protein coupled receptors (GPCRs) comprise one of the largest classes of signalling molecules. A wide diversity of activating ligands induce the active conformation of GPCRs and lead to signalling via heterotrimeric G‐proteins and downstream effectors.

Archaeal protein containing domain of unknown function 2193 undergoes oligomeric reconfiguration upon iron–sulfur cluster binding

open access: yesFEBS Letters, EarlyView.
This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]

open access: yes, 2009
Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.

An ellipsometric study of protein adsorption at the saliva-air interface [PDF]

open access: yes, 1989
At the liquid-air interface of human saliva a protein layer is adsorbed. From ellipsometric measurements it was found that the thickness of the surface layer ranged from 400 to 3600 Å and the amount of protein material adsorbed was 9–340 mg/m2.
