Description

General description

Retention in endoplasmic reticulum 1 (Rer1p) is found in Golgi-compartment. The protein contains four transmembrane domains (TDMs), with the amino and carboxy termini facing the cytosol and recognizes polar amino acids in TMDs of several proteins including sec12p and sec71p.

Specificity

Anti-Rer1 recognizes human, mouse, and rat Rer1.

Application

Anti-RER1 antibody produced in rabbit has been used in:

• immunoblotting
• immunohistochemistry
• immunofluorescence

Anti-RER1 antibody produced in rabbit may be used in immunoblotting, immunofluorescence and immunohistochemical (IHC) techniques. It is used to determine the roles of RER1 in the retention/retrieval of endoplasmic reticulum membrane proteins from the early Golgi compartment.

Biochem/physiol Actions

Retention in endoplasmic reticulum 1 (Rer1) is essential for retrieval of endoplasmic reticulum (ER) membrane proteins from the early Golgi compartment. In addition, mammalian Rer1 is also involved in the ER retention/retrieval of unassembled γsecretase complex subunits. Rer1 interacts with immature nicastrin and unassembled Pen2 through critical residues found in their TMDs. Downregulation of protein expression enhances surface localization of Pen2, whereas Upregulated expression of Rer1 stabilizes unassembled Pen2. Thus, Rer1 regulates the assembly of the γ-secretase complex and therefore contributes to total cellular γ-secretase activity.

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
