MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a secreted activator protein with two cysteine-rich, furin-like domains and one thrombospondin type 1 domain. The encoded protein is a ligand for leucine-rich repeat-containing G-protein coupled receptors (LGR proteins) and positively regulates the Wnt signaling pathway. In mice, the protein induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]
PHENOTYPE: Homozygous inactivation of this gene leads to abnormal ovarian development and masculinized features including pseudohermaphroditism in genital ducts, depletion of fetal oocytes, male-like vascularization, and ectopic testosterone production in the ovaries. [provided by MGI curators]
