Blue native polyacrylamide gel electrophoresis (BN-PAGE) for analysis of multiprotein complexes from cellular lysates.
Multiprotein complexes (MPCs) play a crucial role in cell signalling, since most proteins can be found in functional or regulatory complexes with other proteins (Sali, Glaeser et al. 2003). Thus, the study of protein-protein interaction networks requires the detailed characterization of MPCs to gain an integrative understanding of protein function and regulation. For identification and analysis...
متن کاملTwo-dimensional blue native/SDS gel electrophoresis of multiprotein complexes.
The two-dimensional blue native/sodium dodecyl sulfate polyacrylamide gel electrophoresis (2D BN/SDS-PAGE) is a method of choice for the investigation of protein complexes. This highly resolvent separation method is unique in that it facilitates the identification of many protein complexes simultaneously. Because of its simplicity and suitability, the 2D BN/SDS-PAGE can be now applied to a wide...
متن کاملAnalysis of mitochondrial subunit assembly into respiratory chain complexes using Blue Native polyacrylamide gel electrophoresis.
The mitochondrial respiratory chain consists of multi-subunit protein complexes embedded in the inner membrane. Although the majority of subunits are encoded by nuclear genes and are imported into mitochondria, 13 subunits in humans are encoded by mitochondrial DNA. The coordinated assembly of subunits encoded from two genomes is a poorly understood process, with assembly pathway defects being ...
متن کاملTwo-dimensional Blue native/SDS gel electrophoresis of multi-protein complexes from whole cellular lysates: a proteomics approach.
Identification and characterization of multi-protein complexes is an important step toward an integrative view of protein-protein interaction networks that determine protein function and cell behavior. The limiting factor for identifying protein complexes is the method for their separation. Blue native PAGE (BN-PAGE) permits a high-resolution separation of multi-protein complexes under native c...
متن کاملIn-gel activity staining of oxidized nicotinamide adenine dinucleotide kinase by blue native polyacrylamide gel electrophoresis.
Oxidized nicotinamide adenine dinucleotide (NAD(+)) kinase (NADK, E.C. 2.7.1.23) plays an instrumental role in cellular metabolism. Here we report on a blue native polyacrylamide gel electrophoretic technique that allows the facile detection of this enzyme. The product, oxidized nicotinamide adenine dinucleotide phosphate (NADP(+)), formed following the reaction of NADK with NAD(+) and adenosin...
