Publisher and Date:(Taylor & Francis Inc, 2016)Aubergine is an RNA-binding protein of the Piwi clade functioning in germline in the piRNA pathway that silences transposons and repetitive sequences. Several mutations of this gene exist but they mostly result in truncated proteins or correspond to mutations that also affect neighboring genes. We have generated complete aubergine knock-out mutants that do not disrupt the neighboring genes. These novel mutants are characterized by PCR and sequencing. Their nature is confirmed by female sterility ...

Publisher and Date:(Company of Biologists Ltd, 2015)RNA metabolism controls multiple biological processes and a specific class of small RNAs called piRNAs act as genome guardians by silencing the expression of transposons and repetitive sequences in the gonads. Defects in the piRNA pathway affect genome integrity and fertility. The possible implications in physiopathological mechanisms of human diseases have made the piRNA pathway the object of intense investigation and recent work suggests that there is a role for this pathway in somatic processes ...
