Understanding lists and knowing how to work with them is crucial to getting the most out of YeastMine. This set of short videos explains everything you need to know.
YeastMine allows you to save objects in lists. Typically, these objects are genes, but you can also make lists of other objects such as Gene Ontology terms or PubMed IDs. One way to create a list in YeastMine is to run a query and save the results in a list. Another way is to type in or upload your own list.
Whenever you create a list in YeastMine, you’re immediately presented with information about the genes in the list, such as Gene Ontology and pathway enrichment, interactions, orthologs, and more. This can help you decide what kind of further analysis you’d like to do.
And what if you create a list but then realize that you forgot to include a gene? No worries. It’s easy to edit your saved lists.
Once you have a list of genes, you can feed it into any template query whose name begins with “Gene” to get results for all of the genes in the list. This powerful feature lets you run successive queries to narrow down your results. For example, you could make a list of all the proteins in a given size range, then query that list to see which ones are located in the nucleus, and finally ask how many of these nuclear proteins have human homologs.
And finally, once you’ve created and saved lists you can do a lot of different things with them: combine them, find their intersection, find genes that are not shared between two lists, or find genes that are in one list but not another. This provides a powerful way to combine or compare results from different YeastMine queries.

The eminent Drosophila geneticist Michael Ashburner famously said: “Biologists would rather share their toothbrush than share a gene name.” It’s true that assigning names to genes is often a sticky subject.
In the Saccharomyces cerevisiae community we’re very lucky to have well-defined guidelines for genetic nomenclature, an established system for reserving gene names, and criteria for making them “standard,” or official, names. This system was agreed upon by yeast researchers nearly two decades ago and has served the community well.
Take a look at this video to get an overview of how the gene naming system works. And as always, please contact us with any questions or suggestions.

If you’re not already using YeastMine to answer all your questions about the Saccharomyces cerevisiae genome and the gene products it encodes…you should be!
This versatile tool lets you slice and dice data from SGD in any way you choose. You can ask questions like “How many proteins between 25 and 35 kDa in size are integral to the nuclear membrane?” or “Which genes can mutate to confer oxidative stress resistance, and what biological processes are they involved in?”
Start with this video to see a quick sample of three cool features in YeastMine.

Yeast and humans diverged about a billion years ago, but there’s still enough functional conservation between some pairs of yeast and human genes that they can be substituted for each other. How cool is that?! Which genes are they? What do they do?
This two-minute video explains how to find, search, and download the yeast-human functional complementation data in SGD. You can find help with many other aspects of SGD in the tutorial videos on our YouTube channel. And as always, please be sure to contact us with any questions or suggestions.
