She served as Director and Scientific Member of the Department of Biochemistry at the Max Planck Institute for Developmental Biology in Tübingen, Germany from 2005 until her death in 2018.[1] In 2008, she was awarded the Gottfried Wilhelm Leibniz Prize, shared with Elena Conti, for "fundamental new insights into intracellular RNA transport and RNA metabolism".[2] Together with Conti, she helped characterize proteins important for exporting mRNA out of the nucleus[2] and later in her career she helped elucidate mechanisms of mRNA silencing, translational repression, and mRNA decay.[3] Early life and educationElisa Izaurralde was born in Montevideo, Uruguay on September 20, 1959. At the age of 17 she left Uruguay to pursue an education at Geneva University in Switzerland.[4] After undergraduate training in biochemistry, she went on to receive a PhD in molecular biology in 1989, for work on chromatin organization she performed under the guidance of Ulrich Laemmli.[4][5] CareerAfter receiving her PhD, Izaurralde stayed on in Laemmli's lab for an additional year as a postdoctoral researcher before starting a second postdoctoral position at the European Molecular Biology Laboratory (EMBL) in Heidelberg in 1990, working with Iain Mattaj.[6] It was here that she switched her focus from DNA to RNA and met biophysicist Elena Conti, with whom she would share the 2008 Leibniz Prize.[4] In 1996, she returned to Geneva University, where she led her first work group as a junior research group leader in the Department of Molecular Biology.[4] In this position, she researched the mRNA export factor TAP-p15, before returning to EMBL in 1999, where she extended this line of research together with Elena Conti.[4] Izaurralde worked as a group leader and later a senior scientist at EMBL before becoming Director of the Biochemistry Department at the Max Planck Institute for Developmental Biology in Tübingen, Germany in 2005.[4] She co-organized numerous meetings and conferences including multiple meetings on translational control and non-coding RNA at Cold Spring Harbor Laboratory, EMBO/EMBL Symposia on "The non-coding genome," and the 2010 RNA society meeting.[6] She also served as an editor for a number of scientific journals including the FEBS Journal and PLOS Biology.[6] She was elected to the Board of Directors of the RNA Society in 2004. ResearchIn order to make a protein, genetic information in DNA is copied (transcribed) into messenger RNA (mRNA) in the nucleus and then exported into the cytoplasm, where it is translated into a protein. Much of Izaurralde's early career focused on elucidating how this export occurs at a molecular level.[3] Later in her career, Izaurralde shifted her focus to a different aspect of RNA biology: RNA metabolism - particularly how mRNA molecules are selectively silenced.[3] Her research in this area included studying mRNA silencing, in which microRNA (miRNA) molecules with sequences complementary to sites in the mRNA direct silencing machinery to the mRNA, as well as more general mRNA decay and transcriptional repression mechanisms, and how these processes are interconnected. She discovered a family of scaffolding proteins called GW182 that is important for helping the effector molecule carrying the miRNA (a member of the Argonaute family of proteins) recruit additional silencing co-factors including deadenylase complexes.[7][8] Awards and honors
