piRBaseThe database of various piRNA associated data to support piRNA functional study
piRBase is a manually curated resource of piRNAs, which focused on piRNA function analyses as well as piRNA annotation.
piRBase provides the following information and tools to facilitate piRNA function analyses:
The number of piRNA sequences has reached 173 million, from 264 datasets in 21 organisms.
piRBase classifies piRNAs by biogenesis according to genomic annotation.
Regulatory piRNAs and their mRNA targets are extracted from the literature. Predicted piRNA target lncRNAs are also added to the present release.
piRBase combines DNA methylation data and H3K9me3 data to facilitate studies of piRNA function in epigenetic regulation.
8 types of cancers (Breast, Bladder, Pancreas, Gastric, Liver, Kidney, Myeloma and Colorectal cancer) related piRNAs are included.
Genome Browser provides improved integration and visualization of the relations between piRNA data and other related information.
