RNA Regulatory Elements and Polyadenylation in Plants
Alternative poly(A) site choice (also known as alternative polyadenylation, or APA) has the potential to affect gene expression in qualitative and quantitative ways. APA may affect as many as 82% of all expressed genes in a plant. The consequences of APA include the generation of transcripts with differing 3'-UTRs (and thus differing regulatory potential) and of transcripts with differing prote...
متن کاملSpecificity factors in cytoplasmic polyadenylation
Poly(A) tail elongation after export of an messenger RNA (mRNA) to the cytoplasm is called cytoplasmic polyadenylation. It was first discovered in oocytes and embryos, where it has roles in meiosis and development. In recent years, however, has been implicated in many other processes, including synaptic plasticity and mitosis. This review aims to introduce cytoplasmic polyadenylation with an em...
متن کاملStrange bedfellows: polyadenylation factors at the promoter.
One of the more unexpected discoveries in the field of gene expression during the last few years has been the degree to which transcription of mRNA precursors is coupled to their subsequent processing into mature mRNAs. Much of this linkage involves the transcribing enzyme itself, RNA polymerase II (RNAP II), and specifically the repetitive C-terminal domain of its largest subunit (known simply...
متن کاملThe RNA Helicase Mtr4p Modulates Polyadenylation in the TRAMP Complex
Many steps in nuclear RNA processing, surveillance, and degradation require TRAMP, a complex containing the poly(A) polymerase Trf4p, the Zn-knuckle protein Air2p, and the RNA helicase Mtr4p. TRAMP polyadenylates RNAs designated for decay or trimming by the nuclear exosome. It has been unclear how polyadenylation by TRAMP differs from polyadenylation by conventional poly(A) polymerase, which pr...
متن کاملproficiency level and factors fostering reticence in efl learners
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
