This tail-U-mediated repression (TUMR) is abolished in cells lacking the uridylation enzymes TUT4 and TUT7, indicating that uridylation alters miRNA function by modulating target recognition. We identified a set of non-canonical targets in human cells that are specifically regulated by uridylated miR-27a.

Results from a study on gene expression variability markers in early-stage human embryos shows that TUT7 (ZCCHC6) is a putative expression variability marker for the 3-day, 8-cell embryo stage.

Following an intratracheal challenge with S. pneumoniae, Zcchc6 deficiency led to a modest but significant increase in the expression of select cytokines including IL-6, CXCL1, and CXCL5. These findings were recapitulated in vitro whereby Zcchc6-deficient macrophages exhibited similar increases in cytokine expression due to bacterial stimulation
Title: The RNA uridyltransferase Zcchc6 is expressed in macrophages and impacts innate immune responses.
The authors found that TUT4(7) utilize two multidomain functional modules during the switch from either promoting expression of let-7 microRNA (monoU) or marking it for degradation (oligoU).

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.
