In an in vitro study, led by Grace Gill, PhD, Tufts University School of Medicine, researchers discovered how a protein called SUMO (Small Ubiquitin-related Modifier) guides an enzyme complex that alters the structure of chromatin to regulate expression of genes. Chromatin is a compacted mass of DNA and protein that make up chromosomes. The interaction between SUMO and the enzyme complex is of interest in the study of cancer and neurodegenerative diseases such as Alzheimer's, where aberrant gene expression and altered SUMO function are thought to be indicative of disease...
