Piwi-interacting RNA - Wikipedia
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-interacting RNAs: small RNAs with big functions
2018年11月16日 · 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 proteins to...
PIWI-Interacting RNA: Its Biogenesis and Functions - PubMed
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 the Argonaute family, to form effector complexes known as piRNA-induced silencing complexes, which repress transposons vi …
PIWI-interacting RNAs: who, what, when, where, why, and how
2024年9月26日 · PIWI-interacting RNAs (piRNA) suppress selfish genetic elements and are essential for germ cell biology in animals. They also play critical roles in regeneration in planaria, regulate gene expression in adult mammalian testes, …

2022年9月14日 · PIWI-interacting RNAs (piRNAs) are a class of small non-coding RNAs that associate with proteins of the PIWI clade of the Argonaute family. First identified in animal germ...
An introduction to PIWI-interacting RNAs (piRNAs) in the context …
PIWI proteins and their associated PIWI-interacting RNAs (piRNAs) constitute a small RNA-based adaptive immune system that restricts the deleterious activity of mobile genetic elements to protect genome integrity.
PIWI-interacting RNAs: small RNAs with big functions - PubMed
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 proteins to cleave target RNA, promote heterochromatin assembly and methylate DNA.
PIWI-interacting small RNAs: the vanguard of genome defence
2011年3月23日 · PIWI-interacting RNAs (piRNAs) are a distinct class of small non-coding RNAs that form the piRNA-induced silencing complex (piRISC) in the germ line of many animal species.
PIWI-interacting RNA (piRNA): a narrative review of its …
Initially discovered with the asymmetric division of germline stem cells in the Drosophila ovary, piRNAs have a unique capability to associate with mammalian proteins analogous to P-element induced wimpy testis (PIWI) in Drosophila and are capable of silencing transposons.
Piwi - Wikipedia
The effects of piwi proteins in human and mouse germlines seems to stem from their involvement in translation control as Piwi and the small noncoding RNA, piwi-interacting RNA (piRNA), have been known to co-fractionate polysomes. The piwi-piRNA pathway also induces heterochromatin formation at centromeres, [15] thus affecting transcription. The ...
