A natural ionic liquid: low molecular mass compounds of aggregate glue droplets on spider orb webs [PDF]
, 2022 The aggregate glue of spider orb web is an excellent natural adhesive. Orb-weaver spiders use micron-scale aggregate glue droplets to retain prey in the capture spiral silks of their orb web. In aggregate glue droplets, highly glycosylated and phosphorylated proteins dissolve in low molecular mass compounds.

Lectin affinity-based glycoproteome analysis of the developing xylem in poplar
Forestry Research, 2022 Glycosylation is a significant post-translational modification of proteins, and some glycoproteins serve as players in plant cell wall synthesis and modification.

The stochastic entry of enveloped viruses: Fusion vs. endocytosis [PDF]
Biophys. J., 93, 1116-1123, (2007), 2007 Viral infection requires the binding of receptors on the target cell membrane to glycoproteins, or ``spikes,'' on the viral membrane. The initial entry is usually classified as fusogenic or endocytotic. However, binding of viral spikes to cell surface receptors not only initiates the viral adhesion and the wrapping process necessary for internalization,

Structural basis for the shielding function of the dynamic trypanosome variant surface glycoprotein coat [PDF]
Nature Microbiology 2 (2017), pp. 1523--1532, 2018 The most prominent defence of the unicellular parasite Trypanosoma brucei against the host immune system is a dense coat that comprises a variant surface glycoprotein (VSG). Despite the importance of the VSG family, no complete structure of a VSG has been reported.

Fusogenic structural changes in arenavirus glycoproteins are associated with viroporin activity.
PLoS Pathogens, 2023 Many enveloped viruses enter host cells by fusing with acidic endosomes. The fusion activity of multiple viral envelope glycoproteins does not generally affect viral membrane permeability.

Membrane curvature regulates the spatial distribution of bulky glycoproteins
Nature Communications, 2022 MUC1 is a heavily glycosylated protein on the cell surface. Here the authors show that MUC1 prefers negative over positive membrane curvature due to its bulky size, enabling MUC1 to avoid endocytosis and surface removal based on curvature preference.

Follicle-stimulating hormone receptor: Advances and remaining challenges [PDF]
In: Arun K. Shukla (ed.), dir., G Protein-Coupled Receptors:
Emerging Paradigms in Activation, Signaling and Regulation Part A (p. 1-58).
International Review of Cell and Molecular Biology, 338 (1\`ere ed.). USA :
Elsevier. 171 p. (2018), 2018 Follicle-stimulating hormone (FSH) is produced in the pituitary and is essential for reproduction. It specifically binds to a membrane receptor (FSHR) expressed in somatic cells of the gonads. The FSH/FSHR system presents many peculiarities compared to classical G protein-coupled receptors (GPCRs).
