What is the lifespan of proteins?
This figure increases to 0.5–35 hours in dividing mammalian cells (~24 hour cell cycle) and ~43 hours in non-dividing cells6, 7. Turnover studies in mice (lifespan ~1.5 years) found the average half-lives of proteins in the brain, liver, and blood to be between 3 and 9 days8.
What is the average half-life of a protein?
The majority of the proteins quantified have half-lives within the range of 4–14 hours. About 6% of all quantified proteins (49) have half-lives <4 hours, while 51 proteins have long half-lives (>14 hours); the median half-life is 8.7 hours.
Which protein has the longest half-life?
Among the longest-lived proteins that were reproducibly observed in more than one cell type, we find the two histone family proteins: HIST1H1C and H2AFY. The average half-life in B-cells is 2242 and 971 h, respectively (Fig. 2b, c). This value goes up to 2741 and 1950 h, respectively, in NK cells.
