Endoplasmic Reticulum

Endoplasmic reticulum

A membrane network involved in protein production and processing, lipid synthesis, and calcium storage.

Overview

EXPLORE BY LEVEL

The endoplasmic reticulum, or ER, is a network of membranes inside eukaryotic cells. Some regions help make proteins for membranes or export, and other regions make lipids or store calcium.

The ER is a continuous, dynamic membrane system with specialized domains and cell-type-specific functions. Protein translocation, folding, lipid synthesis, and signaling are coordinated but distinct processes.
