CREB-regulated transcription coactivator 1 (CRTC1), previously referred to as TORC1 (Transducer Of Regulated CREB activity 1), is a protein that in humans is encoded by the CRTC1gene.[1][2][3][4] It is expressed in a limited number of tissues that include fetal brain and liver and adult heart, skeletal muscles, liver and salivary glands[5] and various regions of the adult central nervous system.[6]
Production of CRTC1 is blocked in Alzheimer's disease.[7]
TORC1 might be the target protein in ketamin induced anti-depressent effect via NMDA-antagonisation.
The TORC1 inhibitor drugs dactolisib and everolimus, are being investigated to determine if they can boost the immunity of elderly patients.[8]
