We investigated whether chloroplasts are involved in the gravisensing system of C. richardii prothalli. We used a clumped-chloroplast mutant, clumped chloroplast 1 ( cp1 ), in which the chloroplasts are detached from the plasma membrane and clustered around the nucleus likely because of a partial...
The role of plasma membrane (PM) area as a critical factor during cell motility is poorly understood, mainly due to an inability to precisely follow PM area dynamics. To address this fundamental question, we developed static and dynamic assays to follow exocytosis, endocytosis, and PM area chang...
It is astonishing, however, that very basic functionalities of the plasma membrane have thus far remained enigmatic2. One central open question relates to the role of lipids in modulating interactions between membrane proteins. In this paper we address this question, by measuring, how the presence...

How GPI-anchored proteins turnover: or where do they go after arrival at the plasma membrane. Semin Immunol, 6, 81-8.P. Censullo, M.A. Davitz, How GPI-anchored proteins turnover: or where do they go after arrival at the plasma membrane, Semin. Immunol. 6 (1994) 81-88....
Testisin is expressed in abundance on the sperm plasma membrane, where it has been shown to promote epidydimal sperm maturation and motility important for fertilizing ability [7]. Several of the coagulation and fibrinolytic proteases are found in semen [17,63], and uPA is present on the surfa...
The results demonstrated that laser irradiation destabilized the MLs’ membrane, leading to significantly greater drug release compared to tests simulating hyperthermia at 42 °C. For instance, at 6 h, the sample subjected to 42 °C and pH 5.5 exhibited (17 ± 2)% DOX release, while under ...
This plasma membrane location was blocked in vivo in prenyltransferase mutants and by mevinolin, which inhibits the synthesis of prenyl groups. In addition to the five MUBs with CAAX boxes, Arabidopsis has one MUB variant with a cysteine-rich C terminus distinct from the CAAX box that is ...
(B) Transgenic BY‑2 cells were salt plasmolysed (4% NaCl) for 15 min to demon- strate the relocalization of cell surface GPI‑anchored LeAGP‑1 on plasma membrane (PM) and Hechtian strands (arrow). (Scale bars = 20 mm). Interactions Model of AGPs and Cytoskeleton GPI‑anchored ...
Approximately 1%of plant proteins are predicted to be post-translational y modified with a glycosylphospha-tidylinositol (GPI) anchor that tethers the polypeptide to the outer leaflet of the plasma membrane. Whereas the synthesis and structure of GPI anchors is largely conserved across eukaryotes, ...
