+This track is part of the DANIO-CODE track collection. Most messenger RNAs end in a poly(A) tail, and the position where that tail is added determines the length of the 3' untranslated region. That region carries the binding sites for microRNAs and RNA-binding proteins, so a transcript that uses a different poly(A) site can be regulated quite differently. 3P-seq (poly(A)-position profiling by sequencing) sequences the junction between the transcript and its poly(A) tail, which places the 3' end of the transcript directly.
This track shows 3P-seq data for 15 zebrafish samples covering 7 developmental stages, from the 1-cell stage to the adult. Both the raw signal and the tag clusters called from it are shown. During the first hours of development, when the embryo still lives on maternally deposited RNA, poly(A) tails are actively lengthened and shortened, so these data change substantially from stage to stage.

-The track has two views that can be configured separately. Signal shows one auto-scaled coverage graph per sample; Regions shows the tag clusters as blocks. Nothing is displayed until samples are selected on the configuration page, where they can be filtered by developmental stage and by sample.
The DANIO-CODE consortium assembled 1,802 zebrafish developmental genomics datasets, 1,438 of them already published and 366 generated by consortium members, and reprocessed all of them from the raw sequencing reads so that samples from different
