Welcome to LncRNAWiki 105,256 human long non-coding RNAs inside

Introduction LncRNAWiki is a wiki-based database for management of human lncRNAs, aiming to harness collective intelligence to collect, edit, and annotate information about human lncRNAs. This database is a publicly editable and open-content platform for community curation of human lncRNAs, bearing the potential to become a comprehensive and up-to-date knowledgebase for human lncRNAs. Featured lncRNAs: XXX, XXX, ...... and more Newly added lncRNAs: LUNAR1, a recently discovered lncRNA, is Notch-regulated and functions to enhance IGF1R (insulin-like growth factor receptor 1) mRNA expression to maintain human T cell acute lymphoblastic leukemia (T-ALL). If a lncRNA is newly reported in a published paper but is not found in LncRNAWiki after blast/search, please create a new page for this lncRNA. See here for any help. Community curation: Community-curated efforts are quantified and rewarded by giving explicit authorship. Please share your expertise and perform curations to have the authorship for lncRNAs of your interest. Contribute your efforts, further our knowledge.

Data sources We integrated lncRNA sequences and annotation information from three data sources: GENCODE (version 19; 23,898 human lncRNA transcripts), NONCODE (version 4.0; 95,135 human lncRNA transcripts), and LNCipedia (version 2.1; 32,181 human lncRNA transcripts). After the process of error and redundancy elimination, we at last obtained 105,255 non-redundant lncRNA transcripts. To examine how many lncRNAs have been functionally annotated, we blasted the 105,255 lncRNAs against lncRNA sequences in lncRNAdb (purple circle indicates lncRNAdb) (downloaded on 21 July, 2014; 223 lncRNAs in total) and found at most 103 lncRNAs have been functionally annotated to date, indicating a long-term process of human lncRNA annotation.

Classification Taking into account that the genomic context of lncRNAs may offer insights into their function, the classification of lncRNAs based on genomic location is of great biological significance in in-depth mining and analysis (Ma etal. 2013, RNA Biology). We classified lncRNAs into seven groups (Intergenic, Intronic (S),Intronic (AS),Overlapping (S),Overlapping (AS), Sense and Antisense) based on their genomic location in respect to protein-coding genes.
