Subproteome analysis of the neutrophil cytoskeleton.

ABSTRACT: Neutrophils play a key role in the early host-defense mechanisms due to their capacity to migrate into inflamed tissues and phagocytose microorganisms. The cytoskeleton has an essential role in these neutrophil functions, however, its composition is still poorly understood. We separately analyzed different cytoskeletal compartments: cytosolic skeleton, phagosome membrane skeleton, and plasma membrane skeleton. Using a proteomic approach, 138 nonredundant proteins were identified. Proteins not previously known to associate with the skeleton were: n-acetylglucosamine kinase, phosphoglycerate mutase 1, prohibitin, ficolin-1, phosphogluconate dehydrogenase, glucosidase, transketolase, major vault protein, valosin-containing protein, aldehyde dehydrogenase, and lung cancer-related protein-8 (LC
