MGI Phenotype FUNCTION: This gene encodes a member of the guanylin family and preproprotein that is proteolytically processed to generate a mature protein product. The mature protein product, known as uroguanylin, is an endogenous ligand for the guanylate cyclase-C receptor and may regulate salt and water homeostasis in the intestine and kidneys. Homozygous knockout mice for this gene exhibit impaired sodium chloride excretion and elevated arterial pressure. This gene is present in a gene cluster with a related guanylin family member on chromosome 4. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit elevated blood pressure, increased sodium levels, and reduced sodium, potassium, and fluid excretion following salt loading. [provided by MGI curators]
