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:
1: The number of piRNA sequences has reached 173 million, from 264 datasets in 21 organisms.
2: piRBase classifies piRNAs by biogenesis according to genomic annotation.
3: Regulatory piRNAs and their mRNA targets are extracted from the literature. Predicted piRNA target lncRNAs are also added to the present release.
4: piRBase combines DNA methylation data and H3K9me3 data to facilitate studies of piRNA function in epigenetic regulation.
5: 8 types of cancers (Breast, Bladder, Pancreas, Gastric, Liver, Kidney, Myeloma & Colorectal cancer) related piRNAs are included.
6: Genome Browser provides improved integration and visualization of the relations between piRNA data and other related information.
