Summary: Enables several functions, including RNA binding activity; mRNA cap binding complex binding activity; and protein kinase binding activity. Involved in regulatory ncRNA-mediated gene silencing and sperm DNA condensation. Located in chromatoid body; dense body; and nucleus. Is expressed in several structures, including central nervous system; genitourinary system; hemolymphoid system gland; and lung. Orthologous to human PIWIL1 (piwi like RNA-mediated gene silencing 1).

Data show that ubiquitin-like, containing PHD and RING finger domains, 1 protein (UHRF1) interacts with protein arginine N-methyltransferase 5 (PRMT5) to regulate the repressive histone arginine modifications, and cooperates with the PIWI pathway during spermatogenesis.

we show that mitochondria-anchored TDRKH controls multiple steps of pachytene piRNA biogenesis in mice. TDRKH specifically recruits MIWI, but not MILI, to engage the piRNA pathway. It is required for the production of the entire MIWI-bound piRNA population and enables trimming of MILI-bound piRNAs.

PIWIL1 augments protein translation with PABPC1 in the presence of 3'-UTRs of post-meiotic mRNAs. While both the N-terminal RNA recognition motif (RRM) domain and the central linker region of PABPC1 stimulate translation, only the PIWI Argonaute and Zwille (PAZ) domain of PIWIL1 positively affects translation of reporter mRNAs.
Title: Domain-functional analyses of PIWIL1 and PABPC1 indicate their synergistic roles in protein translation via 3'-UTRs of meiotic mRNAs.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
