tRNA-derived RNA fragment databases | Non-coding transcript data analysis
tRNA-derived RNA fragments (tRFs) are a newly discovered class of micro-RNA-sized small RNAs that are highly abundant in different human and mouse cell lines, mouse tissues and organisms ranging from bacteria to humans. Individual tRFs are generated with precise ends and are not degradation products of the tRNAs.
A database of transfer RNA fragments (tRFs). With over 100 small RNA libraries analyzed, the database currently contains the sequences and read counts of the three classes of tRFs for eight species: R. sphaeroides, S. pombe, D. melanogaster, C. elegans, Xenopus, zebrafish, mouse and human. The database can be searched by tRF ID or tRF sequence, and the results can be limited by organism.
A framework for studying fragments that arise from mitochondrial and nuclear mature transfer RNAs (tRNAs). MINTbase is an easy-to-use resource for accessing information on tRNA fragments (tRFs) and interactively studying them from diverse vantage points using one or more of the five available vistas. Each vista provides distinct functionalities and its output is interconnected to some of the other four vistas, which in turn enables exploration of the active results from multiple angles at any time. The output pages provide filtering and sorting capabilities thereby permitting an interactive study and further filtering of the active results by the user. For example, the user can easily group the results to investigate possible connections to a type of tRF, a specific source tRNA, number of instances in tRNA space, etc. Additionally, several output pages also include links to external databases (e.g. the UCSC Genome Browser, PubMed, etc.) aimed at providing the user with other easily accessible information.
Contains information on plant transfer RNA-derived fragments. PtRFdb is an online repository that provides two user-friendly options to search transfer RNA-derived fragments (tRFs) from different types of keywords. Specifically, it supplies two types of search modules (basic search and advanced search), sequence similarity search (by BLAST) and browse option with data download facility for each search is provided in this database.
