- Plasma Membrane Tethering of the Cortical ER Necessitates Its Finely . . .
In cells with pronounced cortical ER, many processes are likely restricted to the ER-free PM surfaces The membrane contacts created by the polygonal ER mesh sustained by several tubulating proteins generate a closely spaced patchwork of plasma membrane sites accessible to the cytosol (Figure 4 B)
- Programmed cortical ER collapse drives selective ER degradation and . . .
Premeiotic cells displayed ER morphology that is characteristic of mitotic cells, with ER distributed around the cell periphery (cortical ER) and the nucleus (perinuclear ER)
- ER-phagy requires the assembly of actin at sites of contact . . . - PNAS
The mechanisms by which regions of the ER are recognized, severed from the ER network, and processed for degradation through ER-phagy are incompletely understood
- Coordinated cortical ER remodeling facilitates actomyosin ring assembly
Zhang and See reveal that actomyosin forces and active exocytosis are two major driving factors for endoplasmic reticulum (ER)-plasma membrane (PM) contact remodeling during contractile ring assembly
- Programmed cortical ER collapse drives selective ER degradation and . . .
Premeiotic cells displayed ER morphology that is characteristic of mitotic cells, with ER distributed around the cell periphery (cortical ER) and the nucleus (perinuclear ER) As cells progressed through meiosis, the cortical ER underwent a striking series of morphological changes
- Programmed cortical ER collapse drives selective ER degradation and . . .
A subset of the cortical ER collapses away from the plasma membrane at anaphase II, thus separating into a spatially distinct compartment This programmed collapse depends on the transcription factor Ndt80, conserved ER membrane structuring proteins Lnp1 and reticulons, and the actin cytoskeleton
- Different ER–plasma membrane tethers play opposing roles in . . . - PNAS
In yeast, most of the ER is found at the cell cortex, just below the plasma membrane, in the form of a network of highly fenestrated sheets and tubules with several cytoplasmic elements connecting the cortical ER (cER) to the outer nuclear membrane
- cortical endoplasmic reticulum | SGD
Gene Ontology Term: cortical endoplasmic reticulum GO ID GO:0032541 Aspect Cellular Component Description A cortical network of highly dynamic tubules that are juxtaposed to the plasma membrane and undergo ring closure and tubule-branching movements Synonyms cortical ER, ER-PM peripheral junction, peripheral endoplasmic reticulum, peripheral ER
- The mutual influence of microtubules and the cortical ER on their . . .
The statement regarding the reciprocal relationships between the ER and cortical microtubules is substantiated here by two categories of evidence The first piece of evidence was acquired using Total Internal Reflection Fluorescence (TIRF) microscopy and time-lapse movies
- STIM1-induced precortical and cortical subdomains of the endoplasmic . . .
Our results distinguish at least three elements in the formation of cortical ER: precortical structures formed in the cytosol, cortical ER apposed to the PM, and thin cortical ER devoid of ribosomes
