:::ORGANELLE DB::: (219 words)
Organelle DB compiles protein localization data from organisms spanning the eukaryotic kingdom and presents an organized catalog of the known protein constituents of more than 50 organelles, subcellular structures, and protein complexes.
In particular, Organelle DB is a central repository of yeast protein localization data, incorporating results from both previous and current (ongoing) large-scale studies of protein localization in Saccharomyces cerevisiae.
In total, Organelle DB is a singular resource consolidating our knowledge of the protein composition of eukaryotic organelles and subcellular structures.
