Table 1 Ranking GO categories of biological processes according to their mean protein turnover. Shown is a manually curated list of GO categories following a GO category analysis of HeLa proteins of the MS data set. Categories whose median turnover was significantly different from the overall HeLa turnover data set value (2.2) are indicated in the right column

From: Hypothesis: protein and RNA attributes are continuously optimized over time
