| T1 |
0-104 |
Sentence |
denotes |
Insulin-degrading enzyme rapidly removes the beta-amyloid precursor protein intracellular domain (AICD). |
| T2 |
105-247 |
Sentence |
denotes |
The intramembranous gamma-secretase cleavage of the beta-amyloid precursor protein (APP) is dependent on biologically active presenilins (PS). |
| T3 |
248-631 |
Sentence |
denotes |
Notch also undergoes a similar PS-dependent gamma-secretase-like cleavage, resulting in the liberation of the Notch intracellular domain (NICD), which is critically required for developmental signal transduction. gamma-Secretase processing of APP results in the production of a similar fragment called AICD (APP intracellular domain), which may function in nuclear signaling as well. |
| T4 |
632-668 |
Sentence |
denotes |
AICD, like NICD, is rapidly removed. |
| T5 |
669-803 |
Sentence |
denotes |
By using a battery of protease inhibitors we demonstrate that AICD, in contrast to NICD, is degraded by a cytoplasmic metalloprotease. |
| T6 |
804-927 |
Sentence |
denotes |
In vitro degradation of AICD can be reconstituted with cytoplasmic fractions obtained from neuronal and non-neuronal cells. |
| T7 |
928-1218 |
Sentence |
denotes |
Taking into account the inhibition profile and the cytoplasmic localization, we identified three candidate enzymes (neurolysin, thimet oligopeptidase, and insulin-degrading enzyme (IDE), also known as insulysin), which all are involved in the degradation of bioactive peptides in the brain. |
| T8 |
1219-1357 |
Sentence |
denotes |
When insulin, a well characterized substrate of IDE, was added to the in vitro degradation assay, removal of AICD was efficiently blocked. |
| T9 |
1358-1520 |
Sentence |
denotes |
Moreover, overexpression of IDE resulted in enhanced degradation of AICD, whereas overexpression of the inactive IDE E111Q mutant did not affect AICD degradation. |
| T10 |
1521-1603 |
Sentence |
denotes |
Finally, immunodepletion of IDE significantly reduced the AICD degrading activity. |
| T11 |
1604-1793 |
Sentence |
denotes |
Therefore our data demonstrate that IDE, which is one of the proteases implicated in the removal of extracellular Abeta, also removes the cytoplasmic product of gamma-secretase cleaved APP. |
