MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] PIWIL2 belongs to the Argonaute family of proteins, which function in development and maintenance of germline stem cells (Sasaki et al., 2003 [PubMed 12906857]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit decreased testis weight, azoospermia, and male infertility associated with a complete arrest of spermatogenesis and increased apoptotic cell death during the early prophase of the first meiosis. [provided by MGI curators]
