CC -!- FUNCTION: Mediates a somatic signaling mechanism required for the CC maintenance of germline stem cells to produce and maintain a CC daughter germline stem cell. It is not essential for the further CC differentiation of the committed daughter cell. Acts cell CC autonomously to promote germline stem cell division. CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm. Note=Nurse cells, CC follicle cells and oocytes in developing egg chambers. CC -!- TISSUE SPECIFICITY: Expressed somatically in the ovariole terminal CC filament and epithelial sheath cells. Expressed in the germarium CC at low levels during oogenesis stages 1-6, at a lower level during CC stages 7-9, strongly at stage 10 and eventually accumulating in CC early embryos. CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. CC -!- SIMILARITY: Belongs to the argonaute family. Piwi subfamily. CC -!- SIMILARITY: Contains 1 PAZ domain. CC -!- SIMILARITY: Contains 1 Piwi domain.
