| # CalCEN: A Co-Expression Network for *Candida albicans* |
| Elucidating gene function is a major goal in biology, especially among non-model organisms. |
| However, doing so is complicated by the fact that molecular conservation does not always |
| mirror functional conservation, and that complex relationships among genes are responsible |
| for encoding pathways and higher-order biological processes. Co-expression, a promising |
| approach for predicting gene function, relies on the general principle that genes with |
| similar expression patterns across multiple conditions will likely be involved in the |
| same biological process. For *Candida albicans*, a prevalent human fungal pathogen, we |
| leveraged a large amount of publicly available transcriptomic data to generate a C. albicans |
| Co-Expression Network (CalCEN), recapitulating known protein networks, predicting gene function, and |
| enabling insights into the principles influencing co-expression. Overall, co-expression |
| is a powerful tool for uncovering gene function, and decreases the experimental tests |
| needed to identify functions for currently under-annotated genes. |
