New discovery reveals how cohesin complex alters gene expression
DNA
University of Barcelona May 29 2025 Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA and creates specific loops in the genetic material which determine the architecture of the genome and gene expression. Some mutations in the genes of the cohesion complex are responsible for rare diseases (cohesinopathies), such as the Cornelia de Lange syndrome (SCdL) or Roberts syndrome, which affect several organs and cause
