Roux Lab


Primary research focus

Kyle J. Roux, PhD

Our laboratory investigates the structure and function of the mammalian nuclear envelope in health and disease. We have identified and are functionally characterizing several novel members of the LINC-complex. These proteins are retained on the outer nuclear membrane where they appear to perform specific roles in specialized cell types. We are also investigating the mechanisms by which defects in a single constituent of the nuclear lamina, the intermediate filament scaffold inside the nucleus, lead to a wide variety of diseases called laminopathies. These studies are supported by the BioID method to screen for interacting and proximate proteins.

Behind the research

Defects in a cellular structure termed the nuclear envelope are associated with a myriad of diverse diseases, collectively called nuclear envelopathies. Most of these disorders clinically manifest during the first two decades of life and include muscular dystrophy, cardiomyopathy, lipodystrophy, dystonia, neuropathy, skeletal defects, and progeria. The nuclear envelope is situated at a critical juncture in the cell, both intimately associated with the genome and responsible for connecting it to the rest of the cell. While it is clear that mutations in genes encoding protein constituents of the nuclear envelope underlie these diseases, the exact mechanisms remain largely unknown. In part, these nuclear envelopathies involve a nuclear envelope structure called the LINC-complex that is responsible for linking the nucleoskeleton to the cytoskeleton.

Lab News

August 2016, Drs. Roux was awarded a Sanford-Mayo Collaborative Research Grant for the 2016-2017 year. He will be working in partnership with Dr. Paul Galardy at the Mayo Clinic to study the mechanisms by which a regulator of epigenetics and DNA repair affects the progression of neuroblastoma, a common and highly aggressive tumor affecting children.

July 2016, Dr. Kyle Roux was recently recognized with the Faculty and Resident Award for Distinguished Researcher of the Year from the University of South Dakota, Sanford School of Medicine’s Department of Pediatrics. Dr. Roux was recognized for his outstanding research efforts at Sanford Research during the recent Pediatric Residency program graduation banquet.

July 2016, Dr. Kyle Roux and members of his team, Dr. Daein Kim and Sam Jenson, recently published a book chapter that explores novel methods for investigating protein interactions in a cellular organelle known as the nuclear envelope which is a critical cellular structure in a myriad of cellular processes. The chapter, entitled “Identifying Protein-Protein Associations at the Nuclear Envelope with BioID” was published in the 2016 edition of Methods in Molecular Biology.

May 2016, Dr. Kyle Roux was recently invited to the University of Alberta to meet with faculty and discuss his ongoing research and technology development. The title of Dr. Roux’s invited lecture was: “Tracking protein footprints with BioID.”

April 2016, A research publication from the Roux Lab was recently recommended for Faculty of 1000 as being of special significance in its field. F1000Prime publishes recommendations of articles in biology and medicine from a faculty of around 10,000 scientists and clinical researchers aimed at highlighting highly significant research. The article entitled “An improved smaller biotin ligase for BioID proximity labeling” was recently published in the journal Molecular Biology of the Cell.
