MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel, however, it may require other non-pore-forming proteins for activity. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a null mutation reduced urinary flow rates and on a low phosphate diet display an attenuated ability to increase renal phosphate reabsorption. [provided by MGI curators]
