NapRNAdb: a multispecies repository and analytical platform for napRNA discovery and functional annotation

Over 75% of the human genome transcribes noncapped RNAs (napRNAs), which typically function as noncoding RNAs in gene expression regulation. While short napRNAs (e.g. small RNAs) have well-defined transcriptomic roles, long napRNAs with diverse terminal modifications remain poorly characterized. To advance research, we developed NapRNAdb (https://bioinformaticsscience.cn/naprnadb), the first database dedicated to NAP-seq-derived napRNAs, enabling cross-species napRNA transcriptome profiling (40...
