[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.

Repbase Switching to Nonprofit Subscription Model

Soon, GIRI will be relying exclusively on the support of the scientific community in securing consistent, steady growth of Repbase. In the coming months, we will be transitioning to a subscription model, and count on you to help us achieve necessary funding. Since 1992, Repbase relied in part on the funding from governmental grants; however, this option is no longer available. Read More
