Cohesin News and Research

RSS

Cohesin is the protein responsible for binding the sister chromatids during mitosis after S phase. At metaphase, most cohesin is removed, except for some at the centromere. At Anaphase, securin, an inhibitory subunit of separase, is hydrolyzed.

Study reveals how DNA misfolding causes congenital heart disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes for this disorder is having only one functional copy of the gene TBX5, instead of two healthy copies, inherited from parents.

Researchers uncover nuclear organization mechanism linked to Friedreich's ataxia

Researchers have uncovered a fundamental rule that governs how genes are physically arranged inside the cell nucleus, and how disruptions to that organization can contribute to human disease.

Protein complex cohesin found essential for guiding cell identity decisions

Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the three-dimensional structure of the genome, but surprisingly most genes continued to function as usual, Weill Cornell Medicine researchers found.

Multidimensional regulation of stem cell fate by the cohesin complex

Conventional studies on stem cell fates are primarily focused on transcription factors, with the limited consideration for 3D genome architecture.

Researchers uncover how chromosome crossovers protect fertility

When a woman becomes pregnant, the outcome of that pregnancy depends on many things - including a crucial event that happened while she was still growing inside her own mother's womb.

Scientists reveal how rare gene mutations drive schizophrenia risk

Researchers analyzed the largest exome-sequencing dataset to date and identified new rare coding variants and genes linked to schizophrenia risk. The study highlights converging genetic pathways, implicating chromatin organization and GABAergic signaling in schizophrenia neurobiology.

Herpes virus reshapes the human genome's architecture to aid its replication

Viruses are entirely dependent on their hosts to reproduce. They ransack living cells for parts and energy and hijack the host's cellular machinery to make new copies of themselves.

New discovery reveals how cohesin complex alters gene expression

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.

New chromatin tracing method unlocks DNA looping process in high resolution

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves.

Bidirectional movement drives DNA loop formation

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make loops into DNA could move in one direction only. The discovery, which is published in Cell, is key to understanding how these motors shape our genome and regulate our genes.

New discovery reveals twisting action of molecular motors in the DNA

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes.

STAG2 loss linked to increased aggression in Ewing sarcoma

Ewing sarcoma is a tumor of the bones and soft tissues that occurs in children and young people. Like all childhood cancers, it is rare – 9 to 10 cases per million inhabitants per year – but it is very aggressive. 25% of patients do not respond well to regular therapy and they often experience relapses.

Research unveils the dual subdomain structure of the centromere

Researchers from the Kops group in collaboration with researchers from the University of Edinburgh, made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides.

Study uncovers more than one hundred key genes linked to DNA damage

More than one hundred key genes linked to DNA damage have been uncovered through systematic screening of nearly 1,000 genetically modified mouse lines, in a new study published today (14 February) in Nature.

New USC study reveals how DNA loops silence gene activity

The blueprint for human life lies within the DNA in the nucleus of each of our cells. In human cells, around six and a half feet of this genetic material must be condensed to fit inside the nucleus. DNA condensation is not random.

Study illuminates how BRD4 protein directs the spatial organization of DNA within cell nucleus

New research is advancing understanding of certain cancers and complex congenital disorders by illuminating how BRD4, a protein that scientists have studied for years, directs the spatial organization of DNA within the nucleus of the cell, a function critical for stem cell differentiation into muscle cells.
