RPGRIP1L and ciliopathy: The protein RPGRIP1L, encoded by the Rpgrip1l/Ftm/Mks5/Nphp8 (Rpgrip1-like) gene and mutated in patients suffering from deadly ciliopathies (Arts et al., 2007; Delous et al., 2007), is located in the primary cilium transition zone and controls autophagy by inhibiting mTOR signaling (Struchtrup et al., 2018).
