A team of Stowers scientists defines biochemical crosstalk between DNA interacting proteins and their modifications When stretched out, the genome of a single human cell can reach six feet. To package it all into a tiny nucleus, the DNA strand is tightly wrapped around a core of histone proteins in repeating units–each unit known as a nucleosome. To allow access for the gene expression machinery the nucleosomes must open up and regroup when the process is complete. In the May 1,...

Linker histone H1 is important for chromosome structure and gene regulation 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 yesterday's print issue of Genes and Development, also found that this protein class, known as linker histones, works to regulate gene expression in vivo....
