Long noncoding RNAs (lncRNAs) are a type of transcript that is > 200 nucleotides, which have been proven to exert powerful regulatory functions in multiple species and typically lack the ability to codify for proteins. However, increasing evidence shows that lncRNAs are able to encode peptides that exert relevant activities in biological process and diseases. To dig the peptide treasure hidden in lncRNAs, we present a comprehensive database of lncRNA coding peptides across multiple species, LncPep. LncPep totally covers 10,580,228 peptides translated from 883,804 lncRNAs across 39 different species...
