Identifiers represent computationally predicted and experimentally verified translatable circular RNAs (circRNAs) across six model species (human, mouse, rat, worm, fly, and zebrafish), including ribosome-associated circRNAs and their encoded peptides with systematic annotation of sequence, structure, and function.

Pattern for Local Unique Identifiers

Local identifiers in riboCIRC should match this regular expression:
^(hsa|mmu|rno|cel|dme|dre)_ribocirc[A-Za-z0-9.:]+_\d{3}$

Example Local Unique Identifiers
hsa_ribocircSCD_001   Resolve
cel_ribocircF54A3.3_001   Resolve
dme_ribocirccdi_001   Resolve
dre_ribocircim:7151449_001   Resolve
mmu_ribocircCoil_001   Resolve
rno_ribocircVps13b_003   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from riboCIRC should match this regular expression:
^ribocirc:(hsa|mmu|rno|cel|dme|dre)_ribocirc[A-Za-z0-9.:]+_\d{3}$

Example CURIEs
ribocirc:hsa_ribocircSCD_001
ribocirc:cel_ribocircF54A3.3_001
ribocirc:dme_ribocirccdi_001
ribocirc:dre_ribocircim:7151449_001
ribocirc:mmu_ribocircCoil_001
ribocirc:rno_ribocircVps13b_003
Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier hsa_ribocircSCD_001 is used to demonstrate the providers available for riboCIRC. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
