I have a list of mitochondrial genes which are widely distributed on mitochondria and involved in variously biological processes such as TCA, ETC, fatty acid metabolism. I want to describe these genes in a concise way, for example, coloring these genes on a mitochondrial image or automatically classifying these genes according to their function. I have tried some tools based on GO and KEGG but did not find suitable tools. Any tools? Or other way to summarize the list of genes? Thanks!
