Alpha-synuclein - Wikipedia

Alpha-synuclein is a protein that, in humans, is encoded by the SNCA gene. It is abundant in the brain, while smaller amounts are found in the heart, muscle and other tissues. In the brain, alpha-synuclein is found mainly at the tips of neurons in specialized structures called presynaptic terminals. Within these structures, alpha-synuclein interacts with phospholipids and proteins.

The deposition of the amyloid beta-protein (Abeta) is one of the pathological hallmarks of Alzheimer's disease (AD). Abeta-deposits show the morphology of senile plaques and cerebral amyloid angiopathy (CAA). Senile plaques and vascular Abeta-deposits occur first in neocorti-cal areas. Then, they ex …

Methods for analysis of amyloid-beta aggregates. - CORE

To characterize the different Abeta species and to study the aggregation process, a wide range of techniques has been applied over the past years. These techniques aim to visualize the different Abeta species and study their structure, to separate them, and to quantify the aggregated Abeta forms by immunology-based methods.

351 - Gene ResultAPP amyloid beta precursor protein [ (human)]

This gene encodes a cell surface receptor and transmembrane precursor protein that is cleaved by secretases to form a number of peptides. Some of these peptides are secreted and can bind to the acetyltransferase complex APBB1/TIP60 to promote transcriptional activation, while others form the protein basis of the amyloid plaques found in the brains of patients with Alzheimer disease.

Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD). Here, we demonstrate that Abeta-binding alcohol dehydrogenase (ABAD) is a direct molecular link from Abeta to mitochondrial toxicity. Abeta interacts with ABAD in the mitochondria of AD patients and transgenic mice.
