FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a sodium/hydrogen exchanger regulatory cofactor. The protein interacts with and regulates various proteins including the cystic fibrosis transmembrane conductance regulator and G-protein coupled receptors such as the beta2-adrenergic receptor and the parathyroid hormone 1 receptor. The protein also interacts with proteins that function as linkers between integral membrane and cytoskeletal proteins. The protein localizes to actin-rich structures including membrane ruffles, microvilli, and filopodia. Mutations in this gene result in hypophosphatemic nephrolithiasis/osteoporosis type 2, and loss of heterozygosity of this gene is implicated in breast cancer.[provided by RefSeq, Sep 2009]
PHENOTYPE: For one allele homozygous null mice exhibit renal phosphate wasting, reduced fertility and high female mortality rate at birth and postnatally. For a second allele homozygous null mice exhibit hypophosphatemia, increased intestinal goblet cell numbers and abnormal intestinal epithelial cells. [provided by MGI curators]
