Annotating Splice Sites: Workflow

A one-page summary/flowchart of the logic process for identifying appropriate splice sites when annotating.

Annotation of a Drosophila Gene

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.

Annotation of Drosophila Primer

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.

Introduction to BLAST using Human Leptin

Dr. Justin R. DiAngelo (Penn State Berks) and Dr. Alexis Nagengast (Widener University) have developed an exercise that introduces students to the basic functionality of the NCBI web site and NCBI BLAST. Students will use NCBI BLAST to identify the putative orthologs of the human Leptin gene in other species.

About Synteny Analysis

A one-page summary of the logic process used to determine if genes in a fosmid are syntenic with respect to D. melanogaster

Quick Check of Student Annotations

This document describes a protocol that GEP faculty can use to quickly identify potential errors in student gene annotations.
