Database Description

Although the rhesus macaque is a unique model for the translational study of human diseases, currently its use in biomedical research is still in its infant stage due to error-prone gene structures and limited annotations. We performed strand-specific mRNA next-generation sequencing in ten rhesus macaque tissues and generated 1.2 billion 90-bp paired-end long expression tags, covering >97.4% of the putative exon in monkey transcripts annotated by Ensembl. We found that at least 28.7% of the rhesus macaque transcripts were previously mis-annotated, mainly due to incorrect exon-intron boundaries, incomplete UTRs and missed exons. Compared with the previous gene models, the revised transcripts show clearer sequence motifs near splicing junctions and the end of UTRs, as well as cleaner patterns of exon-intron distribution for expression tags and cross-species conservation scores. Strikingly, 1,292 exon-intron boundary revisions between coding exons corrected the previously mis-annotated open reading frames. The revised gene models were experimentally verified in randomly-selected cases. We further integrated functional genomics annotations from >60 categories of public and in-house resources and developed an online accessible database, the RhesusBase (http://www.rhesusbase.org). User-friendly interfaces were developed to update, retrieve, visualize, and download the RhesusBase meta-data, providing a "one-stop" resource for the monkey research community.
