CC -!- FUNCTION: Acts via the piwi-interacting RNA (piRNA) metabolic process,
CC which mediates the repression of transposable elements during meiosis
CC by forming complexes composed of piRNAs and Piwi proteins and governs
CC the methylation and subsequent repression of transposons
CC (PubMed:26808625, PubMed:15817569, PubMed:17346786). Directly binds
CC piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a
CC Dicer-independent mechanism and are primarily derived from transposons
CC and other repeated sequence elements (PubMed:16882972). In ovarian
CC somatic cells, mediates silencing of transposable elements at the
CC transcriptional level in a mael-dependent manner (PubMed:23159368,
CC PubMed:28472469). Involved in silencing of long terminal repeat (LTR)
CC retrotransposons in male germline (PubMed:15817569). In testis,
CC regulates spermatogenesis together with Tudor-SN (PubMed:26808625). In
CC germ cells, mediates silencing at both transcriptional and post-
CC transcriptional levels and is involved in the maintenance of
CC populations of primary and secondary piRNAs. Piwi-mediated
CC transcriptional silencing is accompanied by the formation of His3 'Lys-
CC 9' trimethylated (H3K9me3) euchromatin and heterochromatin
CC (PubMed:23434410, PubMed:23392610). In ovary, associates predominantly
CC with antisense piRNAs that contain uridine at their 5' end. Association
CC with sense piRNAs is also observed but to a lesser extent. Mediates a
CC somatic signaling mechanism required for the maintenance of germline
CC stem cells to produce and maintain a daughter germline stem cell
CC (PubMed:9851978, PubMed:10631171, PubMed:9199372, PubMed:16949822). It
CC is not essential for the further differentiation of the committed
CC daughter cell (PubMed:9851978). Acts cell autonomously to promote
CC germline stem cell division (PubMed:9851978, PubMed:10631171). Its role
CC in stem cell maintenance does not seem to require nuclear localization.
CC Required maternally for the posterior localization of osk and vas and
CC for pole cell formation during oogenesis and early embryogenesis
CC (PubMed:16949822). Together with Hop and Hsp83, mediates canalization,
CC also known as developmental robustness, likely via epigenetic silencing
CC of existing genetic variants and suppression of transposon-induced new
CC genetic variation (PubMed:21186352). Shows RNA cleavage activity,
CC although is not required for any of its known functions
CC (PubMed:9199372, PubMed:16882972, PubMed:23297219). In the ovaries,
CC forms a complex with nxf2, Panx and Nxt1 which acts as effectors of

CC -!- SUBUNIT: In the ovaries, part of a complex composed of at least Panx,
CC nxf2, piwi and Nxt1 (PubMed:26472911, PubMed:26494711, PubMed:31368590,
CC PubMed:31384064). The complex is knowns as Panx-induced co-
CC transcriptional silencing (PICTS) complex, Panx-nxf2-dependent TAP/p15
CC silencing (Pandas complex), SFiNX (silencing factor interacting nuclear
CC export variant) or piwi-Panx-nxf2-p15 (PPNP) complex (PubMed:26472911,
CC PubMed:26494711, PubMed:31368590, PubMed:31384064). Interacts with vas;
CC this interaction is RNA-independent (PubMed:16949822). Interacts with
CC Dcr-1 and Fmr1; these interactions occur in polar granules
CC (PubMed:16949822). Interacts (via N-terminal region) with CBX5 (via
CC chromoshadow domain) (PubMed:17875665). Forms a complex with Hsp83 and
CC Hop; probably Hop mediates the interaction between piwi and Hsp83
CC (PubMed:21186352). Forms a complex with Yb body components armi and
CC fs(1)Yb; this interaction is required for proper piRNA loading and
CC nuclear localization of piwi (PubMed:20966047). Interaction of Piwi and
CC fs(1)Yb is likely to occur via armi (PubMed:20966047). Interacts (via
CC the N-terminal region when unmethylated or symmetrically methylated at
CC Arg-10) with papi (via Tudor domain) (PubMed:21447556,
CC PubMed:29531043). Interacts with vret (PubMed:21831924). Interacts with
CC Panx (PubMed:26472911, PubMed:26494711). Interacts with arx
CC (PubMed:23913921, PubMed:23913922). Interacts with Tudor-SN
CC (PubMed:26808625). Interacts with Nup358 (via N-terminus)
CC (PubMed:29735528). Associates with the nuclear pore complex via
CC interaction with Elys (PubMed:28472469). Interacts with thoc5; the
CC interaction might be partly RNA-mediated (PubMed:28472469). Interacts
CC with xmas-2 (PubMed:28472469). {ECO:0000269|PubMed:16949822,

CC {ECO:0000269|PubMed:28472469}. Note=Component of polar granules.

CC somatically in ovariole terminal filament cells, epithelial sheath
CC cells, cap cells and follicle cells (at protein level). Expressed in
CC nurse cells and oocytes in developing egg chambers (at protein level)
CC (PubMed:29531043, PubMed:29735528). In embryos, accumulates in pole
CC cells (at protein level). In larval and adult testis, expressed in a
CC germinal proliferative center at the apical tip containing somatic hub
CC cells and mitotically dividing germ stem cells (at protein level)
CC (PubMed:26808625). {ECO:0000269|PubMed:10631171,

CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically.
CC Expressed in the germarium, at low levels during oogenesis stages 1-6,
CC at a lower level during stages 7-9, strongly at stage 10, eventually
CC accumulates in early embryos and later in development the expression
CC decreases (at protein level). {ECO:0000269|PubMed:16882972,

CC -!- PTM: Symmetrically dimethylated, most likely by csul (PubMed:19377467,
CC PubMed:29531043). Methylation at Arg-10 enhances binding to papi
CC whereas methylation at Arg-7, Arg-9 or Arg-11 reduces binding affinity
CC to papi (PubMed:29531043). {ECO:0000269|PubMed:19377467,
CC ECO:0000269|PubMed:29531043}.
CC -!- PTM: Phosphorylated on serine and tyrosine residues in an Hsp83-
CC dependent manner. {ECO:0000269|PubMed:21186352}.
CC -!- DISRUPTION PHENOTYPE: Female mutants show normal ovarian development up
CC to third instar larval stage (PubMed:9851978, PubMed:9199372,
CC PubMed:26808625). However, adult mutant ovarioles contain germaria
CC lacking germline cells and containing two normal or abnormal egg
CC chambers as result of the failure of germline stem cell maintenance
CC (PubMed:9851978, PubMed:9199372, PubMed:26808625). In adult testis,
CC results in deregulation of transposon silencing (PubMed:26808625).
