Background

Function：Plays a central role during spermatogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity (By similarity). Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins (By similarity). The PIWIL4-piRNA pathway acts in the nucleus and mediates silencing of active transposons: engages with nascent transposable element transcripts and governs the piRNA-directed DNA methylation and subsequent repression of transposons (By similarity). In contrast to PIWIL1 and PIWIL2, does not show endonuclease activity (By similarity). Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements (By similarity). Associates with secondary piRNAs antisense and PIWIL2/MILI is required for such association (By similarity). The piRNA process acts upstream of known mediators of DNA methylation (By similarity). Plays a key role in the piRNA amplification loop, also named ping-pong amplification cycle, by acting as a 'slicer-incompetent' component that loads cleaved piRNAs from the 'slicer-competent' component PIWIL2 and target them on genomic transposon loci in the nucleus (By similarity). May be involved in the chromatin-modifying pathway by inducing 'Lys-9' methylation of histone H3 at some loci (PubMed:17544373). In addition to its role in germline, PIWIL4 also plays a role in the regulation of somatic cells activities (By similarity). Plays a role in pancreatic beta cell function and insulin secretion (By similarity). Involved in maintaining cell morphology and functional integrity of retinal epithelial through Akt/GSK3alpha/beta signaling pathway (PubMed:28025795). When overexpressed, acts as an oncogene by inhibition of apoptosis and promotion of cells proliferation in tumors (PubMed:22483988)

Subcellular Localization：Nucleus; Cytoplasm

Expression：
Tissue_specificity:Ubiquitously expressed (PubMed:17544373, PubMed:22483988, PubMed:25038252, PubMed:28025795, PubMed:28711973) . Detected in retina, retinal pigment epithelia cells (RPE) (at protein level) (PubMed:28025795)

Induction:Up-regulated in vitreous aspirates of with proliferative diabetic retinopathies (at protein level) . Up-regulated after exposure to oxidative stress and VEGF in adult retinal pigment epithelial cell line (ARPE19 cells) (PubMed:30145353) . Up-regulated in cervical cancer tissues (PubMed:22483988)

Isoforms & Post-Translational Modification：Q7Z3Z4 has 3 isomers: Q7Z3Z4-1: 96589 Da (predicted); Q7Z3Z4-2: 56442 Da (predicted); Q7Z3Z4-3: 52174 Da (predicted).
Arginine methylation by PRMT5 is required for the interaction with Tudor domain-containing protein (TDRD1, TDRKH/TDRD2 and TDRD9) and subsequent localization to the meiotic nuage, also named P granule

Subunit：Interacts with PRMT5 and WDR77. Interacts (when methylated on arginine residues) with TDRD1, TDRKH/TDRD2 and TDRD9. Interacts with MOV10L1 (By similarity).
