N2 - This review focuses on the evolutionary and functional relationship of calcitonin receptor-stimulating peptide (CRSP) with calcitonin (CT)/calcitonin gene-related peptide (CGRP) in mammals. CRSP shows high sequence identity with CGRP, but distinct biological properties. CRSP genes (CRSPs) have been identified in mammals such as pigs and dogs of the Laurasiatheria, but not in primates and rodents of the Euarchontoglires or in non-placental mammals. CRSPs have genomic organizations highly similar to those of CT/CGRP genes (CT/CGRPs), which are located along with CGRPs in a locus between CYP2R1 and INSC, while the other members of the CGRP superfamily, adrenomedullin and amylin, show genomic organizations and locations distinct from CT, CGRP, and CRSP. Thus, we categorized these three peptides into the CT/CGRP/CRSP family. Non-placental mammals having one and placental mammals having multiple CT/CGRP/CRSP family genes suggests that multiplicity of CT/CGRP started at an early stage of mammalian evolution. In the placental mammals, Laurasiatheria generally possesses multiple CRSPs and only one CT/CGRP, while Euarchontoglires possesses CT/CGRP and CGRPβ but no CRSP, indicating an increase in the diversity and multiplicity of this family of genes in mammalian evolution. Phylogenetic analysis suggests that some CRSPs have been generated very recently in mammalian evolution. Taken together, the increase in the number and complexity of the CT/CGRP/CRSP family genes may have due to evolutionary pressure to facilitate adaptation during mammalian evolution. In this regard, it is important to elucidate the physiological roles of CT, CGRP and CRSP from the viewpoint of the CT/CGRP/CRSP family even in Euarchontoglires.
