General Information

Term

mRNA base-pairing post-transcriptional repressor activity

ID (Ontology)

GO:1903231 (Gene Ontology)

Definition

A post-transcriptional repressor activity that acts by base-pairing with an mRNA to prevent gene expression. The binding can result in targeting the mRNA for degradation or interfering with mRNA translation resulting in post-transcriptional gene silencing.[ PubMed:18197166 PubMed:20533884 ]

Also Known As

"mRNA base-pairing posttranscriptional repressor activity" ; "mRNA binding involved in post-transcriptional gene silencing" ; "mRNA binding involved in quelling"
