Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The effect of membrane active agents on human leukaemia cells [PDF]

open access: yes, 1998
This Thesis investigates the effect of membrane-active agents, such as synthetic ether lipids (SEL), local anaesthetics and polyunsaturated fatty acids (PUFAs) on human leukaemia cells.

Characterisation of a synthetic Archeal membrane reveals a possible new adaptation route to extreme conditions

open access: yesCommunications Biology, 2021
By studying the properties of a synthetic membrane mimicking an archaeal membrane and containing the apolar polyisoprenoid squalane, Salvador-Castell et al. show that lipid bilayer stability and functionality are shifted to higher temperatures under high

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Roles of polyunsaturated fatty acids, from mediators to membranes

open access: yesJournal of Lipid Research, 2020
PUFAs, such as AA and DHA, are recognized as important biomolecules, but understanding their precise roles and modes of action remains challenging. PUFAs are precursors for a plethora of signaling lipids, for which knowledge about synthetic pathways and ...

The Interaction between a Synthetic Amphiphilic Polypeptide and Lipids

open access: yesBiophysical Journal, 1982
Most spectroscopic studies designed to examine the interactions between phospholipid and protein molecules in biological membranes have involved measurements of the perturbation of the orientational order of lipids due to the presence of proteins (1).

Interaction of Synthetic Polypeptides with Lipids in Monolayers [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1978
Abstract The interaction of polypeptide (benzyloxycarbonyl derivatives of basic poly(γ-amino acid), benzyl esters of acidic poly(α-amino acid), and poly(l-leucine)) and lipid (fatty acids, fatty alcohols and cholesterol) at the air–water interface was investigated. From the additivity rule of mean molecular areas and the work of collapse

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Synthetic Approaches for Nucleic Acid Delivery: Choosing the Right Carriers

open access: yes, 2019
The discovery of the genetic roots of various human diseases has motivated the exploration of different exogenous nucleic acids as therapeutic agents to treat these genetic disorders (inherited or acquired).
