Pathways Project: Annotation Videos
This series of videos is intended to help GEP students annotate a Pathways Project gene from start to finish.

This exercise will walkthrough an example of annotating a wasp venom gene for the Parasitoid Wasps Project. It will discuss wasp versions of common GEP annotation tools—Genome Browser, Gene Record Finder, and Gene Model Checker—and provide background for the interpretation of data tracks that are unique to the Parasitoid Wasps Project.
This PowerPoint presentation describes the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to NCBI BLAST, web databases, and the issue of reading frames and phase.
This worksheet will guide you through a series of basic steps that have been found to work well for annotation of species closely related to Drosophila melanogaster. It provides a technique that can also be the foundation of annotation in other, more divergent species but in those cases other special techniques will probably be needed.
This walkthrough uses the annotation of a gene on the D. biarmipes Muller F element to illustrate the GEP comparative annotation strategy. This document shows how you can investigate a feature in an annotation project using FlyBase, the Gene Record Finder, and the gene prediction and RNA-Seq evidence tracks on the GEP UCSC Genome Browser. The walkthrough then shows how you can identify the coordinates of each coding exon using NCBI BLAST, and also includes a discussion on the phases of the donor and acceptor splice sites. The walkthrough concludes by verifying the proposed gene model using the Gene Model Checker; it also includes a sample GEP Annotation Report.
This PowerPoint presentation provides a brief primer on the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to RNA-Seq, web databases, and a discussion on the phases of the splice donor and acceptor sites.
The Pathways Project is focused on annotating genes found in well characterized signaling and metabolic pathways across the Drosophila genus. This walkthrough illustrates how to apply the GEP annotation strategy for the Pathways Project to construct a gene model for the Ras homolog enriched in brain (Rheb) gene in Drosophila yakuba.
This exercise was developed by Dr. Anya Goodman (California Polytechnic State University) and Dr. James Youngblom (California State University, Stanislaus). This exercise engages students in annotating genomic DNA from less famous species of Drosophila while teaching basic bioinformatics skills.
Dr. Justin R. DiAngelo (Penn State Berks) has developed an exercise that takes students through a series of steps to annotate a gene in a Drosophila biarmipes contig. Students will construct a gene model using gene predictions, BLASTX searches, and the GEP UCSC Genome Browser mirror. Students will then verify their final gene model using the Gene Model Checker.
