New SGD Help Video: GO Slim Mapper

October 5, 2015


The GO Slim Mapper is a very useful tool that maps specific Gene Ontology (GO) annotations to more general GO terms. This allows you to take a group of genes and bin them into broad categories of function, process, or localization by mapping their GO annotations to broader terms.

Watch our new video to get an overview of how the GO Slim Mapper works:

New SGD Help Video: What is GO?

September 14, 2015


The Gene Ontology (GO) is an integral part of modern biology. It provides a common language that unifies the description of gene products from all organisms, structured in a way that allows very detailed information to be captured while at the same time facilitating broad categorizations. 

Watch our new video for a brief refresher course on GO: what it is, how it’s structured, and why it’s important.

 

SGD Help: Interaction Overview and Network

August 24, 2015


SGD includes data on many thousands of genetic and physical interactions between the genes and proteins of Saccharomyces cerevisiae, as curated by our friends at the BioGRID database. We provide two different graphical displays that help you get a very quick and intuitive overview of known interactions for a particular gene or protein.

All interactions for a gene and its product are listed on its interactions page (see an example). At the top of the page, the Interactions Overview shows at a glance how many interactions have been curated and whether they are physical or genetic. This video explains the details of the Interactions Overview diagram:

Farther down on the Interactions page, the Interaction Network is a visual representation of genetic interactions for a particular gene and the protein-protein interactions for its gene product. The network is interactive, allowing you to choose to view either genetic or physical interactions or both. Using the slider, you can set a minimum number of experiments supporting the interactions displayed. Learn how to use the interactive features of the Interaction Network by watching this brief video:

SGD Help Video: Genome Snapshot

August 10, 2015


Have you ever wondered just how many genes are found in the genome of the S. cerevisiae reference strain S288C, or how well characterized they are? SGD’s Genome Snapshot gives you a graphical overview of the annotation state of the genome, updated daily. This brief video gives you a tour of the page and explains the information shown in each section.
