text: PPARGC1A has been shown to interact with:
  * CREB-binding protein
  * Estrogen-related receptor alpha (ERRα), estrogen-related receptor beta (ERR-β), estrogen-related receptor gamma (ERR-γ).
  * Farnesoid X receptor
  * FBXW7
  * MED1, MED12, MED14, MED17,
  * NRF1
  * Peroxisome proliferator-activated receptor gamma
  * Retinoid X receptor alpha
  * Thyroid hormone receptor beta
  ERRα and PGC-1α are coactivators of both glucokinase (GK) and SIRT3, binding to an ERRE element in the GK and SIRT3 promoters.
