General Information
Term perinuclear endoplasmic reticulum ID (Ontology) GO:0097038 (Gene Ontology)
Definition The portion of endoplasmic reticulum, the intracellular network of tubules and cisternae, that occurs near the nucleus. The lumen of the perinuclear endoplasmic reticulum is contiguous with the nuclear envelope lumen (also called perinuclear space), the region between the inner and outer nuclear membranes.
Also Known As "perinuclear ER"
