Diffusion of human replication protein A along single-stranded DNA.

Replication protein A (RPA) is a eukaryotic single-stranded DNA (ssDNA) binding protein that plays critical roles in most aspects of genome maintenance, including replication, recombination and repair. RPA binds ssDNA with high affinity, destabilizes DNA secondary structure and facilitates binding of other proteins to ssDNA. However, RPA must be removed from or redistributed along ssDNA during ...

A model of sequence-dependent protein diffusion along DNA.

We introduce a probabilistic model for protein sliding motion along DNA during the search of a target sequence. The model accounts for possible effects due to sequence-dependent interaction between the nonspecific DNA and the protein. Hydrogen bonds formed at the target site are used as the main sequence-dependent interaction between protein and DNA. The resulting dynamical properties and the p...

Functional Myc-Max heterodimer is required for activation-induced apoptosis in T cell hybridomas

T cell hybridomas respond to activation signals by undergoing apoptotic cell death, and this is likely to represent comparable events related to tolerance induction in immature and mature T cells in vivo. Previous studies using antisense oligonucleotides implicated the c-Myc protein in the phenomenon of activation-induced apoptosis. This role for c-Myc in apoptosis is now confirmed in studies u...

Opposite orientations of DNA bending by c-Myc and Max.

The control of gene transcription requires specific protein-protein and protein-DNA interactions. c-Myc, the protein product of the c-myc protooncogene, is a member of the basic helix-loop-helix leucine-zipper class of transcription factors. Although c-Myc is able to bind to a specific core hexanucleotide DNA sequence (CACGTG), its precise function in modulating transcription remains unclear. T...

Replication Protein A Prohibits Diffusion of the PCNA Sliding Clamp along Single-Stranded DNA

The replicative polymerases cannot accommodate distortions to the native DNA sequence such as modifications (lesions) to the native template bases from exposure to reactive metabolites and environmental mutagens. Consequently, DNA synthesis on an afflicted template abruptly stops upon encountering these lesions, but the replication fork progresses onward, exposing long stretches of the damaged ...
