Functioni

Regulates mitochondrial shape through facilitating mitochondrial fusion. During spermatogenesis, plays a critical role in PIWI-interacting RNA (piRNA) biogenesis. piRNAs provide essential protection against the activity of mobile genetic elements. piRNA-mediated transposon silencing is thus critical for maintaining genome stability, in particular in germline cells when transposons are mobilized as a consequence of wide-spread genomic demethylation. Has been proposed to act as a cardiolipin hydrolase to generate phosphatidic acid at mitochondrial surface (1 Publication). Although it cannot be excluded that it can act as a phospholipase in some circumstances, it should be noted that cardiolipin hydrolase activity is either undetectable in vitro (1 Publication and 1 Publication), or very low. In addition, cardiolipin is almost exclusively found on the inner mitochondrial membrane, while PLD6 localizes to the outer mitochondrial membrane, facing the cytosol. Has been shown to be a backbone-non-specific, single strand-specific nuclease, cleaving either RNA or DNA substrates with similar affinity (1 Publication and 1 Publication). Produces 5' phosphate and 3' hydroxyl termini, suggesting it could directly participate in the processing of primary piRNA transcripts.4 Publications

Pathology & Biotechi

Disruption phenotypei

Mutant animals are born at the expected Mendelian ratio. Females show no discernible phenotype and are fertile. Males are sterile, because of meiotic arrest during spermatogenesis due to demethylation and subsequent derepression of transposable elements. Effects are caused by defects in primary piRNA biogenesis: in contrast to wild-type cells neither mitochondria nor associated meiotic nuage (named P granule) are aggregated.2 Publications

Expressed in embryonic testis at 16.5 dpc (at protein level). Expressed at low levels in type A and B spermatogonia, increases 5-fold in spermatocytes undergoing meiosis (pachytene spermatocytes), and then decreases again in round spermatids. Expressed at low levels in testes in young mice, peaks from postnatal day 14 to day 29 with the onset of puberty andpersists in adulthood (at protein level).2 Publications
