一般描述

Chapso is a zwitterionic detergent derived from Chaps by the addition of a functional hydroxyl group. It is a nondenaturing zwitterionic detergent with characteristics similar to CHAPS, although it is more soluble due to a more polar head group.

应用

Chapso has been used in a study to assess methods for high-throughput crystallization of membrane proteins. It has also been used in a study to investigate the effects of detergents on the structure of rhomboid proteases in a lipid environment.
具有类似于 CHAPS 特性的非变性两性离子洗涤剂，然而由于具有更强极性的头部基团而更易溶解。适用于内在膜蛋白的增溶。

gamma-Secretase is an aspartic protease that hydrolyzes type I membrane proteins within the hydrophobic environment of the lipid bilayer. Using the CHAPSO-solubilized gamma-secretase assay system, we previously found that gamma-secretase activity was sensitive to the concentrations of detergent and phosphatidylcholine.

Gamma-secretase performs the final processing step in the generation of amyloid-beta (Abeta) peptides, which are believed to be causative for Alzheimer's disease. Presenilins (PS) are required for gamma-secretase activity and the presence of two essential intramembranous aspartates (D257 and D385)

Amyloid beta protein (Abeta), a pathogenic molecule associated with Alzheimer's disease, is produced by gamma-secretase, which cleaves the beta-carboxyl terminal fragment (betaCTF) of beta-amyloid precursor protein in the middle of its transmembrane domain.
