Terminal uridylyltransferase 4 (EC 2.7.7.52; UniProt Q5TAX3; also known as TUTase 4, Zinc finger CCHC domain-containing protein 11) is encoded by the ZCCHC11 (also known as KIAA0191, TUT4) gene (Gene ID 23318) in human. TUTase 4 is an uridylyltransferase that mediates the terminal uridylation of mRNAs with short (less than 25 nucleotides) poly(A) tails, hence facilitating global mRNA decay. It is involved in microRNA (miRNA)-induced gene silencing through uridylation of deadenylated miRNA targets and also acts as a suppressor of miRNA biogenesis by mediating the terminal uridylation of some miRNA precursors, including that of let-7 (pre-let-7), miR107, and miR-143 and miR-200c. It is reported to catalyze the 3' uridylation of miR-26A that targets IL6 transcript to abrogate the silencing of IL6 transcript and promote cytokine expression. It may also participate in toll-receptor signaling by suppressing TRAF6-dependent activation of NF-kappaB.
