Circular RNAs (circRNAs), a novel class of endogenous RNAs, are widespread in eukaryotic cells. Most circRNAs are generated through back-splicing of pre-mRNAs, forming a covalently closed loop structure with no 5' caps or 3' polyadenylated tails. Increasing evidence reveals that circRNAs are widespread in eukaryotes and play important roles in diverse biological processes.

 CircFunBase is a web-accessible database that aims to provide a high-quality functional circRNA resource including experimentally validated and computationally predicted functions. The current version of CircFunBase documents more than 7000 manually curated functional circRNA entries, mainly including Homo sapiens, Mus musculus, etc. CircFunBase provides visualized circRNA-miRNA interaction networks. In addition, a genome browser is provided to present the genome context of circRNAs. As a biological information platform for circRNAs, CircFunBase will contribute for circRNA studies and bridge the gap between circRNAs and their functions.
