Functioni

Co-chaperone required during spermatogenesis to repress transposable elements and prevent their mobilization, which is essential for the germline integrity. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and govern the methylation and subsequent repression of transposons. Acts as a co-chaperone via its interaction with HSP90 and is required for the piRNA amplification process, the secondary piRNA biogenesis. May be required together with HSP90 in removal of 16 nucleotide ping-pong by-products from Piwi complexes, possibly facilitating turnover of Piwi complexes.3 Publications

Disruption phenotypei

Males mice are sterile and aspermic due to abnormal pachytene spermatocytes, characterized by the appearance of unusual inclusion bodies and dense compacted nuclei. Spermatocytes fail to proceed beyond the pachytene stage due to abnormal pairing and misalignments between homologous chromosomes, non-homologous partner switches and autosynapsis of X chromosome cores in meiotic spermatocytes. No other abnormalities are detected in any tissues of males. Females mice are fertile (PubMed:12764197). Spermatocytes show derepressed LINE-1 retrotransposon and reduced DNA methylation due to deficient nuclear accumulation of Miwi2 (PubMed:22902560).2 Publications
