Roles of DNA Packaging Protein Revealed By Einstein Scientists

Scientists at Albert Einstein College of Medicine of Yeshiva University have found that a class of **chromatin proteins** is crucial for maintaining the structure and function of **chromosomes** and the normal development of **eukaryotic organisms**. The research, reported in print issue of **Genes and Development**, also found that this protein class, known as linker **histones**, works to regulate **gene expression** in vivo. H1 is one of the five histones — proteins that help to "package" the DNA within chromosomes. All organisms whose cells contain a nucleus — from yeast to humans — have histones in their nuclei.
