What's a GeneRIF?

7SB ribosomal RNA can be oligoadenylated by an unknown enzyme and/or oligouridylated by TUT4/7 and subsequently processed by Dis3l2 and Eri1.
Title: Exonuclease requirements for mammalian ribosomal RNA biogenesis and surveillance.
data demonstrate how degradation of histone mRNAs is initiated when 3' oligouridylation creates a cis element that enables Eri1 to process the double-stranded stem-loop structure
Title: Eri1 degrades the stem-loop of oligouridylated histone mRNAs to induce replication-dependent decay.
Mouse Eri1 regulates miRNA homeostasis in lymphocytes and is required for normal NK-cell development and antiviral immunity.
Title: Eri1 regulates microRNA homeostasis and mouse lymphocyte development and antiviral function.
The roles of meri-1 (mouse enhanced RNAi) and adar1 in the regulation of RNA interference are reported.
Title: High doses of siRNAs induce eri-1 and adar-1 gene expression and reduce the efficiency of RNA interference in the mouse.
Findings indicate that Eri1 catalyzes the final trimming step in 5.8S rRNA processing, functionally and spatially connecting this regulator of RNAi with the basal translation machinery.
Title: Mouse Eri1 interacts with the ribosome and catalyzes 5.8S rRNA processing.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
