Gene ontology (GO) cellular location terms for the cytosolic proteins identified in isolated proximal convoluted tubules. Only proteins that were annotated with a cellular location (348 of 471 identified) are represented here. Sections colored blue contain proteins that should be enriched to be retained in the cytosolic fraction. Proteins were grouped into the “other” category if there were fewer than 3 proteins sharing the same cellular location annotation.
