Examples and Highlights
Example 1
show
FAA4 and its ten most confident interactors.
FAA4 in yeast is a long chain fatty acyl-CoA synthetase; see it connected to other synthetases as well as regulators.
Example 2
show
The 20 most frequently mutated human cancer genes.
These have a higher-than-expected degree of interconnectivity, and are enriched in characteristic molecular functions.
Example 3
show
A poorly characterized protein from Methanosaeta.
It has no annotated domains or functions, but shows some intriguing connections to possible DNA-replication or -repair proteins.

Proteins with Values/Ranks - Functional Enrichment Analysis
Submit your entire experiment as a list of proteins - no cutoffs.
Behind each protein, put a meaningful value for ranking (fold-change, log-pvalue, abundance, ...).
