γ-Secretase cleaves at multiple sites within the transmembrane domain of APP, generating Aβ peptides ranging in length from 38 to 43 residues (4). PubMed:18650430
As mentioned above, γ-secretase processing of APP also releases AICD (Fig. 1). PubMed:18650430
Abeta is generated from b-amyloid precursor protein (APP) through sequential cleavages first by beta-secretase and then by gamma-secretase complex PubMed:21214928
APP alphaCTF and betaCTF are further cleaved by gamma-secretase to generate p83 and Abeta, respectively PubMed:21214928
In addition to cleaving APP CTFs, gamma-secretase cleaves a series of functionally important transmembrane proteins, including Notch [120], cadherin [114], tyrosinase [121], ErbB4 [79], CD44 [70], etc.) (see review [122]) PubMed:21214928

The processing of APP to generate Abeta is executed by beta- and gamma-secretase and is highly regulated PubMed:22122372
APP C83 is further cleaved by gamma-secretase to release a P3 peptide and the AICD, both of which are degraded rapidly PubMed:22122372
gamma-Secretase further cleaves C99 to release AICD and the amyloidogenic Abeta peptide which aggregates and fibrillates to form amyloid plaques in the brain PubMed:22122372
gamma-Secretase cleaves APP at multiple sites and in sequential steps to generate Abeta peptides of different lengths (Fig. 1). The majority of Abeta peptides produced are 40 amino acids long, however, peptides ranging from 38 to 43 amino acids are found in vivo PubMed:22122372

Accordingly, various AICDs (C50, C53, C57 and C59) can be generated during these multi-site cleavages executed by gamma-secretase. However, all of the endogenous AICD forms are rarely detected, probably because of their very rapid degradation (Lu et al. 2000; Passer et al. 2000; Sastre et al. 2001; Yu et al. 2001; Sato et al. 2003) PubMed:22122372
Abeta, an important player in AD, is derived from beta-amyloid precursor protein (APP) through sequential cleavages by beta- and gamma-secretases: APP is cleaved by beta-secretase (BACE1) to generate the large secreted derivative sAPPbeta and the membrane-bound APP C-terminal fragment-beta; the latter can be further cleaved by gamma-secretase to generate Abeta and APP intracellular domain. Alternatively, APP can be cleaved by alpha-secretase within the Abeta domain, which precludes Abeta production and instead generates secreted sAPPalpha that has been shown to be neuroprotective PubMed:24590577

Under normal conditions, Aβ production in brain parenchyma results from hydrolyzing amyloid precursor proteins via beta-secreted enzymes and gamma-secreted enzymes, and the most common subtypes of Aβ in human body are Aβ1–40 and Aβ1–42 PubMed:29626319
