"Functionally defined and derived adenylate–uridylate rich element (ARE) consensus sequences have been shown to exist in the 3′UTR of selected mRNAs belonging to interferons, cytokines and proto-oncogenes ( 1 ). A 13-bp ARE motif was computationally derived from a list of functionally labile ARE-mRNAs and was the basis of the ARE-mRNA database (ARED) which contains GenBank entries where the 3′UTR matches the motif ( 2 )."[1]

Human genes

Main article: Human genes

The ARE-mRNA database (ARED) "demonstrated that ARE-mRNAs represent as much as 5–8% of human genes and encode functionally diverse proteins that are important in many transient biological processes including cell growth and differentiation, signal transduction, transcriptional and translational control, hematopoiesis, apoptosis, nutrient transport, and metabolism ( 2 )."[1]

"The 3′UTRs were searched for the 13-bp pattern WWWUAUUUAUWW with mismatch=−1 which was computationally derived as previously described ( 2 ). The pattern was further statistically validated against larger sets of mRNA data (10 872 mRNA with 3′UTR; GenBank 119) showing occurrence of the motif in 6.8% of human mRNA."[1]

"The ARED website ( http://rc.kfshrc.edu.sa/ared ) offers a query search engine that allows searches for ARE-genes using multiple identifier numbers or descriptions such as UniGene IDs, UniGene definition, RefSeq IDs, accession numbers, alternative names, official Gene symbols and mouse homologs (MGD) ( 10 )."[1]

Gene expressions

Main article: Gene expressions

"3′ untranslated regions play an important role in regulating mRNA fate by complexing with RNA binding proteins that help control mRNA localization, translation, and stability [1, 2, 3]. Identification of a consensus UUAUUUAU sequence in the 3′ UTRs of human and mouse mRNAs encoding tumor necrosis factor (TNF-α) and a variety of other inflammatory mediators led to the suggestion that these AU-rich elements AREs) could be important for regulating gene expression [4]. Subsequent studies confirmed that these and other AREs interact with ARE-binding proteins such as AUF1 (also known as hnRNPD), HuR and other Hu family proteins, and the CCCH zinc finger-containing RBPs ZFP36 (tristetraprolin), ZFP36L1, and ZFP36L2 [5], to alter mRNA degradation and protein expression [6]. In most cases, AREs have been reported to destabilize mRNAs, although in some cellular contexts certain AREs and ARE-binding proteins have been shown to stabilize mRNAs [6, 7]. Subsequent analyses of the human genome concluded that as many as 58% of human genes code for mRNAs that contain AREs [8, 9, 10], suggesting that these elements play a major role in regulating expression of a large group of genes."[2]

Interactions

Main article: Interaction gene transcriptions

"Chen and Shyu [11] divided AREs into two classes of AUUUA-containing AREs and a third class of non-AUUUA AREs. Class I AUUUA-containing AREs had 1-3 copies of scattered AUUUA motifs coupled with a nearby U-rich region or U stretch, whereas class II AUUUA-containing AREs had at least two overlapping copies of the nonamer UUAUUUA(U/A)(U/A) in a U-rich region. Non-AUUUA AREs had a U-rich region and other unknown features, and the relationship of these sequences to AUUUA-containing AREs remains poorly understood. Subsequent studies based on analyses of a set of 4884 AUUUA-containing AREs led to a new classification based primarily on the number of overlapping AUUUA-repeats [8, 9, 10]. This classification system, with five clusters distinguished by the number of repeats, was used to identify AUUUA-containing AREs in the human genome. AREs identified using this classification were found to be abundant in 3′ UTRs of human genes."[2]

Consensus sequences

Binding site for

Constitutive "decay elements (CDEs) [4, 18][...] are conserved stem loop motifs that bind to the proteins Roquin and Roquin2, resulting in increased mRNA decay [18]. CDEs include an upper stem-loop sequence of the form UUCYRYGAA flanked by lower stem se- quences. Lower stem sequences are formed by 2-5 nt pairs of reverse-complementary sequences (e.g. CCUUCYRYGAAGG has a lower stem length of 2)."[2]
