In animals, PIWI-interacting RNAs (piRNAs) of 21–35 nucleotides in length silence
transposable elements, regulate gene expression and fight viral infection. piRNAs guide …

PIWI-interacting RNAs (piRNAs) and their associated PIWI clade Argonaute proteins
constitute the core of the piRNA pathway. In gonadal cells, this conserved pathway is crucial …

Piwi interacting RNAs (piRNAs) constitute novel small non-coding RNA molecules of
approximately 24–31 nucleotides in length that often bind to members of the piwi protein …

MicroRNAs (miRNAs) are small non-coding RNAs that function as guide molecules in RNA
silencing. Targeting most protein-coding transcripts, miRNAs are involved in nearly all …

The PIWI-interacting RNA (piRNA) pathway is a conserved defense mechanism that protects
the genetic information of animal germ cells from the deleterious effects of molecular …

PIWI-interacting RNAs (piRNAs) are a class of small RNAs that are 24–31 nucleotides in
length. They associate with PIWI proteins, which constitute a germline-specific subclade of …

Small-RNA-guided gene regulation has emerged as one of the fundamental principles in
cell function, and the major protein players in this process are members of the Argonaute …

Small RNA molecules regulate eukaryotic gene expression during development and in
response to stresses including viral infection. Specialized ribonucleases and RNA-binding …

Argonaute proteins are conserved throughout all domains of life. Recently characterized
prokaryotic Argonaute proteins (pAgos) participate in host defense by DNA interference …

Non-coding RNAs generally form ribonucleoprotein (RNP) complexes with their partner
proteins to exert their functions. Small RNAs, including microRNAs, small interfering RNAs …
