                                  "In light of the shorter half-life of USP2 (compared to that of PER1) (XREF_FIG) and of its rhythmic expression peaking almost simultaneously with that of PER1, the deubiquitination of PER1 by USP2 could be restricted to a specific circadian time and therefore be altering the function and/or localization of PER1 to fine tune the molecular clock in physiological conditions."
