Figure S1 sraKO mutant flies display normal morphology in axonal projections from PDF-expressing circadian pacemaker neurons.

Figure S2 sraKO mutation decreases PER and TIM levels in PDF-expressing circadian pacemaker neurons. Adult fly brains were dissected at ZT23 in LD cycles.

Figure S3 A transgenic reporter for sra promoter activity (sra-Gal4) is expressed in various brain regions of adult fly.

Figure S4 sra depletion in PDF-expressing clock neurons is sufficient to dampen rhythm amplitude in free-running circadian locomotor behaviors.

Figure S5 Conditional depletion of sra in PDF-expressing neurons causes poor rhythmicity in free-running locomotor behaviors.

Figure S6 Genomic deletion of each calcineurin subunit weakens rhythm amplitude in free-running circadian locomotor behaviors.

Figure S7 Pharmacological inhibition of calcineurin reduces the steady-state levels of PER and TIM, but not CLK proteins, in Drosophila S2 cells.
