[Our mission: To understand the processes altering the genetic makeup of different organisms as well as their biological and medical impact.]

The Genetic Information Research Institute (GIRI), founded in 1994 by Dr. Jerzy Jurka, is a private, nonprofit institution devoted to the study and characterization of repetitive or mobile DNA elements in eukaryotic species. The Institute maintains and develops Repbase, also known as Repbase Update, a database of representative repetitive sequences from eukaryotic species. Repbase is being used worldwide as the reference standard for annotating the presence of repetitive DNA in genomic data. GIRI publishes Repbase Reports, a monthly e-journal that reports newly identified repetitive DNA elements, which are subsequently stored and shared in Repbase. GIRI also provides computational tools (Censor and RepbaseSubmitter) and online services for screening and submission of the repeats.

The Jerzy Jurka Memorial Symposium

This year’s FASEB Mobile DNA in Mammalian Genomes conference features The Jerzy Jurka Memorial Symposium: Comparative and Evolutionary Genomics, chaired by Prof. Mark Batzer of LSU. The memorial symposium will communicate both science and reflections on Dr. Jurka’s life and career.

Help us shape the future of Repbase by participating in a survey
May 27, 2017
As you may have noticed already, we redesigned our website. One of the improvements for this upgrade was adding in Downloads the "Repeatmasked genomes". Currently, we offer repeat maps and repeat-masked genomes for human(hg38) and mouse(mm10). Other genomes will follow once data is mature and stable. To meet specific needs of the users, for each species we provide the results both from RepeatMasker and Censor. You can download the files here.
