Collisions between yeast chromosomal loci in vivo are governed by three layers of organization

Article Abstract:

Collisions between Saccharomyces cerevisiae chromosomal loci, collisions controlled in vivo by three layers of organization, are discussed. A genetic assay for Cre/loxP site-specific recombination was used to find relative probabilities that different pairs of chromosomal loci will collide in vegetatively growing diploid yeast cells.

PTB/nPTB switch: A post-transcriptional mechanism for programming neuronal differentiation

Article Abstract:

A novel post-transcriptional mechanism for programming neuronal differentiation was studied. A switch occurs in expression of a pair of related splicing regulators, known as polypyrimidine tract-binding proteins (PTB) and neural PTB (nPTB) during neuronal differentiation.
