Summary
Enables calcitonin receptor activity. Acts upstream of or within several processes, including adenylate cyclase-activating G protein-coupled receptor signaling pathway; negative regulation of ossification; and osteoclast differentiation. Located in acrosomal vesicle and cilium. Is expressed in several structures, including brain; gonad; limb long bone; mammary gland primordium; and sensory organ. Human ortholog(s) of this gene implicated in osteoporosis. Orthologous to human CALCR (calcitonin receptor). [provided by Alliance of Genome Resources, Jul 2025]
Expression

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
