MGI Phenotype Strain: 2159609;2159620
FUNCTION: This gene encodes a member of the inositol polyphosphate-5-phosphatase (INPP5) family. This protein hydrolyzes the 5' phosphate from phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol-1,4,5-trisphosphate, which results in changes to multiple signaling pathways. This protein may be involved in protein trafficking and secretion. Homozygous knockout mice exhibit impaired spermatogenesis and male sterility. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Nov 2014]
PHENOTYPE: Homozygous null male mice are infertile with a disruption in spermatogenesis and a defect in adherens junctions processing. [provided by MGI curators]
