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.
