The field of epigenomics has been transformed by chromatin immunoprecipitation approaches that provide for the localization of a defined protein or posttranslationally modified protein to specific chromosomal sites. While these approaches have helped us conceptualize epigenetic mechanisms, the field has

Recombineering is a recombination-based highly efficient method of genetic engineering. It can be used to manipulate the bacterial chromosomal DNA as well as any episomal DNA. Recombineering can be used to insert selectable or nonselectable DNA fragments and subclone DNA

Promoter-specific transcriptional activators (activators) stimulate transcription through direct interactions with one or more components of the transcription machinery, termed the "target." The identification of direct in vivo targets of activators has been a major challenge. Previous studies have provided evidence

The genome is nonrandomly organized within the nucleus, but it remains unclear how gene position affects gene expression. Silenced genes have frequently been found associated with the nuclear periphery, and the environment at the periphery is believed to be refractory

Galactokinase (GALK, EC 2.7.1.6) is a cytosolic enzyme with a wide occurrence across the taxonomic kingdoms. It catalyzes the phosphorylation of α-d-galactose (Gal) to α-d-Gal-1-P. The cytotoxicity of free (unphosphorylated) Gal is well documented in plants and causes marked defects.
