MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the calcitonin family of peptide hormones. This hormone is released from pancreatic beta cells following food intake to regulate blood glucose levels and act as a satiation signal. Human patients with type 1 and advanced type 2 diabetes exhibit reduced levels of the encoded hormone in blood and pancreas. This protein also exhibits a bactericidal, antimicrobial activity. [provided by RefSeq, Jul 2016]
PHENOTYPE: Homozygous inactivation of this locus increases glucose tolerance in a gender-dependent manner and results in decreased bone density due to increased bone resorption. [provided by MGI curators]
