- endoplasmic reticulum-Golgi intermediate compartment
A complex system of membrane-bounded compartments located between endoplasmic reticulum (ER) and the Golgi complex, with a distinctive membrane protein composition; involved in ER-to-Golgi and Golgi-to-ER transport.
- ER retention sequence binding
Binding to an endoplasmic reticulum (ER) retention sequence, a specific peptide sequence that ensures a protein is retained within the ER.
- endoplasmic reticulum cisternal network maintenance
The organization process that preserves the endoplasmic reticulum (ER) cisternal network in a stable functional or structural state. The ER cisternal network is the ER part that comprises the membranes with low curvature in cross-section.
- endoplasmic reticulum tubular network maintenance
The organization process that preserves the endoplasmic reticulum (ER) tubular network in a stable functional or structural state. The ER tubular network is the ER part that comprises the membranes with high curvature in cross-section.
- endoplasmic reticulum tubular network formation
The aggregation, arrangement and bonding together of a set of components to form the endoplasmic reticulum (ER) tubular network. The ER tubular network is the ER part that comprises the membranes with high curvature in cross-section.
- endoplasmic reticulum cisternal network assembly
The aggregation, arrangement and bonding together of a set of components to form the endoplasmic reticulum (ER) cisternal network. The ER cisternal network is the ER part that comprises the membranes with low curvature in cross-section.
- protein retention in ER lumen
The retention in the endoplasmic reticulum (ER) lumen of soluble resident proteins. Sorting receptors retrieve proteins with ER localization signals, such as KDEL and HDEL sequences or some transmembrane domains, that have escaped to the cis-Golgi network and return them to the ER. Abnormally folded proteins and unassembled subunits are also selectively retained in the ER.
