چکیده

Effects of sequence disorder on looping and cyclization of the double-stranded DNA are studied theoretically. Both random intrinsic curvature and inhomogeneous bending rigidity are found to result in a remarkably wide distribution of cyclization probabilities. For short DNA segments, the range of the distribution reaches several orders of magnitude for even completely random sequences. The ensemble averaged values of the cyclization probability are also calculated, and the connection to the recent experiments is discussed.

Poly(dA:dT)-Rich DNAs Are Highly Flexible in the Context of DNA Looping

Large-scale DNA deformation is ubiquitous in transcriptional regulation in prokaryotes and eukaryotes alike. Though much is known about how transcription factors and constellations of binding sites dictate where and how gene regulation will occur, less is known about the role played by the intervening DNA. In this work we explore the effect of sequence flexibility on transcription factor-mediat...

A Generalized Theory of DNA Looping and Cyclization

We have developed a generalized semi-analytic approach for efficiently computing cyclization and looping J factors of DNA under arbitrary binding constraints. Many biological systems involving DNA-protein interactions impose precise boundary conditions on DNA, which necessitates a treatment beyond the Shimada-Yamakawa model for ring cyclization. Our model allows for DNA to be treated as a heter...

Role of boundary constraints in DNA cyclization

We modify the classical Shimada-Yamakawa theory of DNA looping by generalizing the form of boundary constraints. This generalization is important in the context of DNA cyclization experiments since it mimics the reduced local rigidity of the ”nicked” DNA loop. Our results indicate that the non-trivial boundary constraints may be responsible for the existing dramatic discrepancy between various ...

Studying DNA looping by single-molecule FRET.

Bending of double-stranded DNA (dsDNA) is associated with many important biological processes such as DNA-protein recognition and DNA packaging into nucleosomes. Thermodynamics of dsDNA bending has been studied by a method called cyclization which relies on DNA ligase to covalently join short sticky ends of a dsDNA. However, ligation efficiency can be affected by many factors that are not relat...

The thermodynamics of DNA loop formation, from J to Z.

The formation of DNA loops is a ubiquitous theme in biological processes, including DNA replication, recombination and repair, and gene regulation. These loops are mediated by proteins bound at specific sites along the contour of a single DNA molecule, in some cases many thousands of base pairs apart. Loop formation incurs a thermodynamic cost that is a sensitive function of the length of loope...
