Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables piRNA binding activity. Involved in retrotransposon silencing; secondary piRNA processing; and spermatogenesis. Acts upstream of with a positive effect on retrotransposon silencing by heterochromatin formation. Located in nucleus and piP-body. Is expressed in embryo; germ cell of testis; testis; and trunk unsegmented mesenchyme. Orthologous to human PIWIL4 (piwi like RNA-mediated gene silencing 4).
