Myoinhibiting neuropeptide. In larvae, both myosuppressin and myosuppressin(2-10) are expressed in the CNS but not the midgut, thoracic perisympathetic organs (tPSO) and abdominal perisympathetic organs (aPSO). Myosuppressin is expressed in the ring gland (at protein level). In adults, myosuppressin is expressed in brain, cardiaca, corpora allata and thoracic-abdominal ganglion (at protein level). Detected in larvae and adults. Belongs to the myosuppressin family.
