Search PolyA_DB


PolyA_DB version 3.1 catalogs polyA sites (PASs) in genomes using deep sequencing data.Gene annotations are mainly based on NCBI Gene and RefSeq databases, and supplemented by the Ensembl database. Strand-specific RNA-seq data are used to extend the 3' end of genes. PASs are identified using data from the 3' end region extraction and sequencing (3'READS) method. Syntenic regions across human, mouse and rat are used to annotate conserved PASs in mammals.
