A cortical network of highly dynamic tubules that are juxtaposed to the plasma membrane and undergo ring closure and tubule-branching movements. [ GOC:se http://www.ncbi.nlm.nih.gov/pubmed/17686782 http://www.ncbi.nlm.nih.gov/pubmed/10931860 ]
Synonyms: cortical ER
Term information
The dynamic nature of the cortical ER and the movements it undergoes (branching and ring closure) has been shown in both yeast and mammalian cells, so appears highly conserved. (PMID:10931860)
