Summaries for PIWIL1 Gene

Entrez Gene Summary for PIWIL1 Gene

  • This gene encodes a member of the PIWI subfamily of Argonaute proteins, evolutionarily conserved proteins containing both PAZ and Piwi motifs that play important roles in stem cell self-renewal, RNA silencing, and translational regulation in diverse organisms. The encoded protein may play a role as an intrinsic regulator of the self-renewal capacity of germline and hematopoietic stem cells. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

GeneCards Summary for PIWIL1 Gene

PIWIL1 (Piwi Like RNA-Mediated Gene Silencing 1) is a Protein Coding gene. Among its related pathways are Dorso-ventral axis formation and Mitotic Prophase. GO annotations related to this gene include nucleic acid binding and mRNA binding. An important paralog of this gene is PIWIL3.

UniProtKB/Swiss-Prot for PIWIL1 Gene

  • Endoribonuclease that plays a central role in postnatal germ cells by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Directly binds methylated 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. Not involved in the piRNA amplification loop, also named ping-pong amplification cycle. Acts as an endoribonuclease that cleaves transposon messenger RNAs. Besides their function in transposable elements repression, piRNAs are probably involved in other processes during meiosis such as translation regulation. Probable component of some RISC complex, which mediates RNA cleavage and translational silencing. Also plays a role in the formation of chromatoid bodies and is required for some miRNAs stability.

  • Isoform 3: May be a negative developmental regulator (PubMed:12037681, PubMed:16287078).
