Protein-coding gene in the species Homo sapiens
Small integral membrane protein (SMIM) 20 is a protein that in humans is encoded by the SMIM20 gene .[5] prohormone to the peptide hormone phoenixin which was discovered for the first time in 2013 in rodent sensory ganglia.[6]
In the study of the evolution of nervous systems , SMIM20 together with NUCB2 have been found to have deep homology across all lineages that preceded creatures with central nervous systems, bilaterians , cnidarians , ctenophores , and sponges as well as in choanoflagellates.[7] [8]
