Small integral membrane protein 20 (SMIM20) is a protein that in humans is encoded by the SMIM20gene.[5] SMIM20 acts as a prohormone to the peptide hormone phoenixin (PNX) which was discovered for the first time in 2013 in rodent sensory ganglia.[6] Two alternate cleavage sites within SMIM20 results in two different phoenixin products, Phoenixin-14 (PNX-14) and Phoenixin-20 (PNX-20).[7]
