Two hypervariable minisatellite DNA binding proteins.
Hypervariable minisatellite DNA sequences are short, tandemly repeated sequences present at numerous loci in eukaryotes. They stimulate intermolecular homologous recombination up to 13-fold in human cells in culture and may be specific sites for the initiation of recombination in the eukaryotic genome (Wahls, W.P., Wallace, L.J., & Moore, P.D. (1990) Cell 60, 95-103). Reported here is the detec...
متن کاملSingle-stranded DNA-binding Proteins
The emergence of DNA as the predominant hereditary material of life has necessitated the evolution of proteins whose sole function is the maintenance and care of these vital molecules. In a typical cell, there is a wide array of proteins with specialized functions in DNA metabolism that allow the cell to maintain and replicate its genome. In order to copy or make repairs to DNA, the double heli...

The Saccharomyces cerevisiae CDC43 gene product is involved in establishing cell polarity during the cell-division cycle. When grown at restrictive temperatures, temperature-sensitive cdc43 mutants are unable to form buds and display delocalized cell-surface deposition [Adams et al., J. Cell Biol. (1990) in press]. We have isolated a cdc43-complementing plasmid from a yeast genomic-DNA library ...
متن کاملBinding specificity of the two major DNA-binding proteins in human serum.
The two major DNA-binding proteins of human serum (DNA-binding protein 1 and DNA-binding protein 2) were shown to bind preferentially to single-stranded polynucleotides rich in guanine residues. Equilibrium competition experiments using a nitrocellulose filter assay system containing labeled human lymphocyte DNA and various competing natural and synthetic polynucleotides indicated that both pro...
متن کاملComparative footprinting of DNA-binding proteins
MOTIVATION Comparative modelling is a computational method used to tackle a variety of problems in molecular biology and biotechnology. Traditionally it has been applied to model the structure of proteins on their own or bound to small ligands, although more recently it has also been used to model protein-protein interfaces. This work is the first to systematically analyze whether comparative m...
