Characterization of AtDGK2 in relation to Contact Sites
García-Hernández, Selene; Ruiz-Lopez, Noemi; Botella-Mesa, Miguel Angel (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 ... -

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 ... -
How are DGK1 and DGK2 involved in membrene contact sites?
Garía-Hernández, Selene; Ruiz-Lopez, Noemi; Botella-Mesa, Miguel Angel (Reunión Biología de Plantas Hispano Luso, 2021-07-07)
Eukaryotic cells have regions of interaction between two organelles where some proteins, which act as tether, bring both membranes closer (10-30 nm) without fusion, named membrane contact sites (MCS). Two organelles that ... -
Identification of NTMC2T5, a new lipid transfer protein family at ER-chloroplast contact sites involved in stress response
Huercano, Carolina; Percio, Francisco; Sanchez-Vera, Victoria; Morello-López, Jorge; Salas-Liñán, Joaquín J; Ruiz-Lopez, Noemi[et al.] (2022-09)
Plants are sessile organisms and they have perfected a complex molecular signalling network to detect and respond to different environmental stresses. In plants, fatty acid synthesis takes place at chloroplasts, and they ... -
IDENTIFICATION OF SYT1 INTERACTORS CONNECTS CALCIUM SIGNALING, ENDOPLASMIC RETICULUM BENDING, PLASMODESMATA AND MEMBRANE CONTACT SITES
Benítez de la Fuente, Francisco; Perez-Sancho, Jessica; Huércano Rubens, Carolina; Amorim-Silva, Vitor; Macho, Alberto; Bayer, Emmanuelle M.; de Jaeger, Geert; Ruiz-Lopez, Noemi; Botella-Mesa, Miguel Angel[et al.] (2021)
Synaptotagmin1 (SYT1) is an Arabidopsis thaliana protein essential for tolerance to several abiotic stresses (Schapire et al., 2008; Pérez-Sancho et al., 2015; Ruiz-Lopez et al., 2020). SYT1 forms endoplasmic reticulum-plasma ... -
Localization and characterization of SMP-containing proteins in Membrane Contact Sites
Huércano Rubens, Carolina; Sánchez-Vera, Victoria; Percio, Francisco; Morello-López, Jorge; Botella-Mesa, Miguel Angel; Ruiz-Lopez, Noemi[et al.] (2021)
Membrane contact sites (MCS) are discrete regions where two membranes from different organelles are closely apposed (10-30 nm). In those regions, non-vesicular transfer of lipids takes place to ensure proper organelle ... -
NTMC2T5 protein family: newly identified ER-chloroplast contact site proteins involved in abiotic stress.
Plants are sessile organisms and therefore they have perfected a complex molecular signalling network to detect and respond to the different environmental stresses such as high temperatures, salinity, or drought. In plants, ... -
NTMC2T5: lipid transfer proteins at ER-chloroplast contact sites involved in plant stress.
Chloroplasts are the site of fatty acid synthesis in plants; however, these fatty acids are assembled into glycerolipids at the ER. Later on, some of these ER-assembled glycerolipids will be transferred back to the ... -

Salas-Liñán, Joaquín J; Cuevas Corral, Oliver; Morello-Lopez, Jorge; Ruiz-Lopez, Noemi; Huércano, Carolina (2022)
In plants, fatty acid synthesis takes place at chloroplasts, and they are assembled into glycerolipids and sphingolipids at the endoplasmic reticulum (ER). Then, the newly synthetized lipids in the ER are delivered to ... -
