AIFM1, also known as Apoptosis Inducing Factor (AIF), is a widely expressed flavoprotein that plays an important role in caspase-independent apoptosis. AIF normally exists in the mitochondrial intermembrane space.

Nuclear lamina is a layer of cross-linked fibrin network that commonly exists in higher eukaryotic cells. It is interior to the nuclear envelope with a fiber diameter of about 10 nm. The nuclear lamina of higher animals are usually composed of three intermediate filament polypeptides – lamins A, B, and C. The nuclear lamina is closely related to the stability of nuclear envelopes, maintenance of nuclear pore location, stabilizing interphase chromatin morphology and spatial structure, chromatin construction, and nuclear assembly.
