Subcellular proteomics, which includes isolation of subcellular components prior to a proteomic analysis, is advantageous not only in characterizing large macro-molecular complexes such as organelles but also in elucidating mechanisms of protein transport and organelle biosynthesis. Because of the high sensitivity achieved by the present proteomics(More)
Sta is an antigen of the human MNSs blood group system carried by a variant glycophorin residing in the erythrocyte membrane. We examined the structure, organization, and inheritance of Sta gene identified in genomic DNA from an Oriental family. Southern blotting detected a useful genetic marker tightly linked to the Sta gene. Differential hybridization and(More)
As a model for the molecular structure of proteins belonging to the alpha 2-macroglobulin family, ovomacroglobulin of reptilian origin was studied by electron microscopy in the original tetrameric form as well as in the dissociated forms into half- and quarter molecules. The following aspects of the molecular internal structure which had previously not been(More)
Structural and immunochemical studies of glycophorins isolated from erythrocytes of an individual homozygous for the M Sta blood group phenotype are described. Reactivities with specific monoclonal antibodies indicated that two major M and N glycophorins were present. The M and N Sta glycophorins were resolved by Lens culinaris lectin affinity(More)
A high molecular weight actin-binding protein was isolated from the Physarum polycephalum plasmodia. The protein ( HMWP ) shares many properties with other high molecular weight actin-binding proteins such as spectrin, actin-binding protein from macrophages, and filamin. It has a potent activity to cross-link F-actin into a gel-like structure. Its(More)
The glycophorin locus (GYP) on the long arm of chromosome 4 encodes antigens of the MNSs blood group system and displays considerable allelic variation among human populations. The genomic structure and organization of a variant glycophorin allele specifying a novel Miltenberger (Mi)-related phenotype, MiX, were examined. This variant probably arose from a(More)
