Die g-Sekretase ist eine der beiden Proteasen, die für die Entstehung des Alzheimer-verursachenden Amyloid b-Peptids (Ab) verantwortlich sind. Ein genaues Verständnis der Ab Entstehung ist von entscheidender Bedeutung, um die Krankheit therapeutisch anzugehen. Der Alzheimer Forschungspreis der Hans und Ilse Breuer-Stiftung unterstützt unsere Forschungsaktivitäten in der tiefgreifenden funktionellen und strukturellen Charakterisierung der g-Sekretase in wesentlichem Maße. Dieses ehrgeizige Projekt konzentriert sich auf die Reinigung der g-Sekretase und die Analyse ihrer molekularen Architektur, auf die Rolle von modulatorisch-wirkenden Interaktoren der g-Sekretase, wie CD147 und TMP21, auf die Identifizierung zusätzlicher g-Sekretase Modulatoren, auf die Identifizierung und Charakterisierung von g-Sekretase Substrat- und Modulator-Bindungsstellen, sowie auf Struktur-Funktions-Analysen der einzelnen g-Sekretase Untereinheiten.
