Considering the full name of NPCT, aminoprocalcitonin, is too long and contains no connotation of biological functions, as well as its evolutionarily conserved amino acid sequence, extensive CNS distribution, fundamental roles in regulating energy homeostasis, and potential translational value for neurological diseases, we would like to propose a new nomenclature of this peptide, which is Calenerin. The prefix Cal- originates from the name of calcitonin, representing that it belongs to the calcitonin gene-encoding peptide family. The gene discussed is CALCA; the disease is nervous system disorder.
