PIWI proteins play a crucial role in fertility and germline development across animals and ciliates. Recently identified as a polar granule component, PIWI proteins appear to control germ cell formation so much so that in the absence of PIWI proteins there is a significant decrease in germ cell formation.
Piwi-interacting RNA (piRNA) is the largest class of small non-coding RNA molecules expressed in animal cells. [1] [2] [3] piRNAs form RNA-protein complexes through interactions with piwi-subfamily Argonaute proteins.
Piwi-like protein 1 is a protein that in humans is encoded by the PIWIL1 gene. [5] [6] [7]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.
Argonaute proteins bind different classes of small non-coding RNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs) and Piwi-interacting RNAs (piRNAs). Small RNAs guide Argonaute proteins to their specific targets through sequence complementarity (base pairing), which then leads to mRNA cleavage, translation inhibition, and/or the ...

Right: The PIWI domain of an Argonaute protein in complex with double-stranded RNA. The active components of an RNA-induced silencing complex (RISC) are endonucleases called Argonaute proteins, which cleave the target mRNA strand complementary to their bound siRNA. [6]
