Characterization of AtDGK2 in relation to Contact Sites
García-Hernández, Selene; Ruiz-López, Noemí
; Botella-Mesa, Miguel Ángel (2019-05-17)
Contact Sites are conserved cellular regions where two membranes of different organelles are very close but not merged. Contact sites between the endoplasmic reticulum (ER) and the plasma membrane (ER-PM CS) play important ... -
Concerted Role of Synaptotagmin 1 and Diacylglycerol Kinases 1 and 2 During Stress Response at ER-PM Contact Sites.
(UMA Editorial, 2025)Los sitios de contacto de membranas (MCS) son regiones en las que dos membranas de orgánulos distintos están cercanas sin llegar a fusionarse, permitiendo funciones esenciales como el transporte de lípidos y la señalización ... -
Concerted transport and phosphorylation of diacylglycerol at ER–PM contact sites regulate phospholipid dynamics during stress.
García-Hernández, Selene; Morello-López, Jorge; Haslam, Richard; Amorim-Silva, Vitor; Moya-Cuevas, José; Catalá, Rafael; Michaelson, Louise; Pérez-Sancho, Jessica; Marković, Vedrana; Salinas, Julio; Napier, Johnathan; Jaillais, Yvon; Ruiz-López, Noemí; Botella-Mesa, Miguel Ángel[et al.] (PNAS, 2025-06-02)
A universal response of plants to environmental stresses is the activation of plasma membrane (PM) phospholipase C, which hydrolyzes phosphoinositides to produce soluble inositol phosphate and diacylglycerol (DAG). Because ... -
Diacylglycerol transport by Arabidopsis Synaptotagmin 1 at ERplasma membrane contact sites under abiotic stress.
Ruiz-López, Noemí; Pérez-Sancho, Jessica; Esteban del Valle, Alicia; García-Hernández, Selene; Huércano Rubens, Carolina; Percio-Vargas, Francisco; Benítez de la Fuente, Francisco; Osorio-Algar, Sonia; Steffen, Vanneste; Lothar, Willmitzer; Napier, Johnathan A.; Perea, Carlos; Salinas, Julio; Amorim-Silva, Vitor; Botella-Mesa, Miguel Ángel[et al.] (2019-11-13)
Bulk lipid transport between membranes within cells involves vesicles, however membrane contact sites have recently been discovered as mediators of non-vesicular lipid transfer. ER-PM contact sites are conserved structures ... -
Role of Arabidopsis DGK1 and DGK2 in cold stress
García-Hernández, Selene; Ruiz-López, Noemí; Botella-Mesa, Miguel Ángel (2022-09-14)
There are regions, present in all eukaryotic cells, where the membranes of two different organelles are very close (10-30nm), but without fusion, due to proteins which act as tether. These regions are named Membrane Contact ... -
Synaptotagmins at the endoplasmic reticulum-plasma membrane contact sites maintain diacylglycerol homeostasis during abiotic stress
Ruiz-López, Noemí; Pérez-Sancho, Jessica; Esteban del Valle, Alicia; Haslam, Richard P.; Vanneste, Steffen; Catalá, Rafael; Perea-Resa, Carlos; Van Damme, Daniël; García-Hernández, Selene; Albert, Armando; Vallarino, José; Lin, Jinxing; Friml, Jiří; Macho, Alberto P; Salinas, Julio; Rosado, Abel; Napier, Johnathan A.; Amorim-Silva, Vitor; Botella-Mesa, Miguel Ángel[et al.] (Oxford University Press in behalf of American Society of Plant Biologists, 2021-05-04)
Endoplasmic reticulum–plasma membrane contact sites (ER–PM CS) play fundamental roles in all eukaryotic cells. Arabidopsis thaliana mutants lacking the ER–PM protein tether synaptotagmin1 (SYT1) exhibit decreased PM integrity ... -
Undercovering the molecular mechanisms of lipid signalling at ER-PM contact sites in tomato (Solanum lycopersicum) under abiotic stress conditions
García-Hernández, Selene; Ruiz-López, Noemí; Benítez de la Fuente, Francisco; Botella-Mesa, Miguel Ángel (2019-01-11)
Abiotic stresses cause large reductions in crop production. Therefore, is important to understand how plants respond in order to develop varieties with increased resistance. Lipid-transport proteins (LTP) are emerging as ...
