(Submitter supplied) The precise control of microRNA (miRNA) biogenesis is important for various cellular functions, and its dysregulation is often associated with human diseases. We previously reported that Terminal uridylyl transferase 4 (TUT4) down-regulates let-7 miRNA biogenesis by oligo-uridylating let-7 precursor (pre-let-7) in mouse embryonic stem cells and that a pluripotency marker Lin28 promotes a processivity of TUT4. more...

(Submitter supplied) Terminal uridylyl transferases (TUTs) function as integral regulators of microRNA (miRNA) biogenesis by modifying the end structure of precursor miRNA (pre-miRNA). Using biochemistry and deep sequencing techniques, we here investigate the mechanism how human TUT7 recognizes and uridylates pre-miRNAs. We show that the overhang of a pre-miRNA is the key structural element that TUT7 and its paralogues, TUT4 and TUT2, recognize. more...

(Submitter supplied) Uridylation occurs pervasively on mRNAs in mammals, yet its mechanism and significance remain unknown. Here we identify TUT4 and TUT7 (also known as ZCCHC11 and ZCCHC6, respectively) as the enzymes that uridylate mRNAs. Uridylation readily occurs on deadenylated mRNAs that are not associated with poly(A) binding protein (PABPC1) in cells. Consistently, purified TUT4 and TUT7 (TUT4/7) selectively uridylate RNAs with short A tails (< ~25 nt) while PABPC1 antagonizes uridylation of polyadenylated mRNAs in vitro. more...

(Submitter supplied) Recent small RNA sequencing data has uncovered extensive modification of the 3’ end of mature microRNAs (miRNAs). This non-templated nucleotide addition can impact miRNA gene regulatory networks through the control of miRNA stability or by interfering with the repression of target mRNAs. The miRNA modifying enzymes responsible for this regulation remain largely uncharacterized. Here we describe the ability for two related terminal uridyl transferases (TUTases), Zcchc6 (TUT7) and Zcchc11 (TUT4), to 3’ mono-uridylate a specific subset of miRNAs involved in cell differentiation and Hox gene control. more...

(Submitter supplied) Many microRNAs (miRNAs) exist alongside abundant miRNA isoforms (isomiRs), most of which arise from post-maturation sequence modifications, such as 3’ uridylation and adenylation. However, the ways in which these sequence modifications affect miRNA function remain poorly understood. To this aim, we have generated knock-out cell lines of TUT4, TUT7 and TENT2 (TUT2), and obtained miRNA profiles from total RNA, AGO1, and AGO2 immunoprecipitations. more...

(Submitter supplied) Strand selection is a critical step in microRNA (miRNA) biogenesis. Although the dominant strand may alter depending on cellular contexts, the molecular mechanism and physiological significance of such alternative strand selection (or “arm switching”) remain elusive. Here we find miR-324 as one of the strongly regulated miRNAs by arm switching, and identify terminal uridylyl transferases TUT4 and TUT7 as the key regulators. more...

(Submitter supplied) TUT4 and TUT7 are terminal uridyl transferases that adds uridine bases to the 3′ end of RNAs such as miRNAs and mRNAs. The overall aim of this experiment was to identify differentially regulated mRNAs and miRNAs in catalytic knockouts of TUT4/7 relative to the wildtype. Catalytic mutants of TUT4/7 was generated in the prostate cancer cell line DU145 and the ovarian cancer cell line IGROV1. As the miRNA regulation by TUT4/7 depends on the oncoprotein LIN28A, LIN28A was lentivirally integrated in the LIN28A- DU145-derived lines and control. more...

However, the ways in which these sequence modifications affect miRNA function remain poorly understood. Here, using human miR-27a in cell lines as a model, we have discovered that a nonfunctional target site unable to base pair extensively with the miRNA seed sequence can regain function when an upstream adenosine is able to base-pair with a post-transcriptionally added uridine in the miR-27a tail. more...

(Submitter supplied) Uridylation of diverse RNA species represents an emerging theme in post-transcriptional gene regulation. In the microRNA pathway, such modifications regulate small RNA biogenesis and stability in plants, worms and mammals. Here, we report the first uridylyltransferase that acts on small RNAs in Drosophila, which we refer to as Tailor. Tailor is the source for the majority of 3´ end-modifications in microRNAs and predominantly targets precursor-hairpins. more...
