    • The inositol trisphosphate receptor in the control of autophagy 
      Criollo Céspedes, Alfredo; Vicencio, José Miguel; Tasdemir, E.; Maiuri, M. C.; Lavandero González, Sergio; Kroemer, Guido (LANDES BIOSCIENCE, 2007-07)
      The second messenger myo-inositol-1,4,5-trisphosphate (IP3) acts on the IP3 receptor (IP3R), an IP3-activated Ca2+ channel of the endoplasmic reticulum (ER). The IP3R agonist IP3 inhibits starvation-induced autophagy. The ...
