WebThe cytoplasmic polyadenylation element (CPE) is a nucleotide sequence within the 3′ UTR of mRNAs which binds to the CPE-binding protein (CPEB). A highly conserved … WebMar 31, 2024 · Critical regulatory elements that encode signals for transport, anchoring and translational regulation including signals for regulating cytoplasmic polyadenylation (cytoplasmic polyadenylation elements: CPE) are present in the 3′-untranslated region (3′UTR) of mRNA. how long before staining treated wood

Cytoplasmic Polyadenylation Element Binding Protein

There is polyadenylation in the cytosol of some animal cell types, namely in the germ line, during early embryogenesis and in post-synaptic sites of nerve cells. This lengthens the poly(A) tail of an mRNA with a shortened poly(A) tail, so that the mRNA will be translated. These shortened poly(A) tails are often … See more Polyadenylation is the addition of a poly(A) tail to an RNA transcript, typically a messenger RNA (mRNA). The poly(A) tail consists of multiple adenosine monophosphates; in other words, it is a stretch of RNA that … See more Function In nuclear polyadenylation, a poly(A) tail is added to an RNA at the end of transcription. On mRNAs, the poly(A) tail protects the mRNA molecule from enzymatic degradation in the cytoplasm and aids in … See more For many non-coding RNAs, including tRNA, rRNA, snRNA, and snoRNA, polyadenylation is a way of marking the RNA for degradation, at least in yeast. This polyadenylation is … See more Although polyadenylation is seen in almost all organisms, it is not universal. However, the wide distribution of this modification and the fact that it is present in organisms from all three domains of life implies that the last universal common ancestor of all living organisms, it … See more RNAs are a type of large biological molecules, whose individual building blocks are called nucleotides. The name poly(A) tail (for … See more Many protein-coding genes have more than one polyadenylation site, so a gene can code for several mRNAs that differ in their 3′ end. The 3’ region of a transcript contains many polyadenylation signals (PAS). When more proximal (closer towards 5’ end) … See more In many bacteria, both mRNAs and non-coding RNAs can be polyadenylated. This poly(A) tail promotes degradation by the degradosome, which contains two RNA-degrading … See more WebJun 5, 2012 · Interestingly, cytoplasmic polyadenylation waves are reinforced by positive translation feedback loops that activate the synthesis of components of the cytoplasmic polyadenylation machinery (such ... WebJun 14, 2013 · Cytoplasmic polyadenylation itself is therefore only one function of a family of RNP complexes that can also mediate translational repression, deadenylation, and mRNA localization. 54, 55, 70, 87 In the rest of this review we focus on the components of these complexes that determine which mRNAs are targeted by cytoplasmic polyadenylation, … how long before starlings fledge
