  • Mouse brain and liver tissue extracts were prepared using N-PER (87792 Thermo Scientific) and T-PER (78510 Thermo Scientific) protein extraction reagents, respectively.
  • Loading control: blots were stripped and re-probed for Beta-actin to ensure equal loading of lysates.
  • 1. Total protein extracts were boiled in 1X SDS Sample Buffer containing 1% SDS and 1.25% Beta-mercaptoethanol at 95°C for 5 minutes prior to loading.
  • 2. 24 µg of boiled extracts were loaded and resolved on a 8-16% SDS-polyacrylamide gel.
  • 3. The Spectra Multicolor Broad Range molecular mass marker (26634 Thermo Scientific) was used as a standard.
  • 4. Proteins were transferred onto PVDF membrane by tank transfer and protein transfer was confirmed with Ponceau S staining.
  • 5. The immunoblot membrane was blocked in PBS containing 3% (W/V) non-fat dry milk at room temperature for 1 hour.
  • 6. The membrane was rinsed with PBS containing 0.05% Tween-20 once.
  • 7. The membrane was immersed with the protein side up in the antibody solution in PBS containing 1% (W/V) non-fat dry milk and incubated for 2 hours at room temperature (~26°C).
  • 8. The membrane was rinsed in PBS containing 0.05% Tween-20 thrice for 10 min each.
  • 9. The membrane was incubated in the HRP-conjugated secondary antibody solution in PBS containing 1% (W/V) non-fat dry milk and incubated for 1 hour at room temperature (~26°C) with gentle agitation.
  • 10. The membrane was rinsed in PBS containing 0.05% Tween-20 thrice for 10 min each.
  • 11. The membrane was washed in PBS twice for 30 seconds each.
  • 12. Signals were detected with Pierce ECL Western Blotting Substrate (32109, Thermo Scientific). The blot was scanned for 300 seconds.
  • 13. The membrane was rinsed three times with PBS containing 0.05% Tween-20.
  • 14. Incubated in Acidic Glycine Stripping Buffer at room temperature with gentle agitation for 3 times, 10 min each.
  • 15. The membrane was washed in PBS containing 0.05% Tween-20 times for 10 min each.
  • 16. Repeated Steps 5-12 with the loading control antibody (for Beta-actin) and its matching secondary antibody.

Transcription factor that binds and activates the promoter of thyroid specific genes such as thyroglobulin, thyroperoxidase, and thyrotropin receptor. Crucial in the maintenance of the thyroid differentiation phenotype. May play a role in lung development and surfactant homeostasis. Activates the transcription of GNRHR and plays a role in enhancing the circadian oscillation of its gene expression. Represses the transcription of the circadian transcriptional repressor NR1D1 (By similarity).
