MicroRNA editing in seed region aligns with cellular changes in hypoxic conditions RNA editing is a finely tuned, dynamic mechanism for posttranscriptional gene regulation that has been thoroughly investigated in the last decade The impact of miRNA seed types on target downregulation Previous studies have identified several major types of canonical miRNA target sites, including those matching to the 6mer, 7mer, or 8mer miRNA seed sequences (Table 2)Sequence conservation analysis suggested that target sites pairing to longer miRNA seeds are more conserved across species and thus areAn online tool for the detection of miRNA polymorphisms in vertebrates miRNA SNiPer accepts a list of miRNA genes and returns a table of variations within different regions of miRNA genes premiRNA, mature, seed region MirSNP is a collection of human SNPs in predicted miRNA

Specifically, seedbased canonical target recognition was dependent on the GC content of the miRNA seed For miRNAs with low GC content of the seed region, noncanonical targeting was the dominant mechanism for target recognition This region is known as "seedregion" and found at the 27 base of the miRNA This region is able to suppress the target mRNAs without having a complete base pairing at the 3'end of the miRNA Another class involves the improper complementary base pairing at the 5'end of the miRNAs, but to overcome this imperfect pairing, there areMiRNA This interaction between the miRNA and 39 UTR is dependent upon a 6–8 nucleotide sequence found in the 59 end of the miRNA called the ''seed'' sequence This sequence must have perfect complementarity with its 39 UTR binding site for repression to occur Disruption of the seed region of the miRNA
MiRNA seed region is more critical than the 3′ region for target recognition in A thaliana (Mallory et al, 04) Moreover, plant and algal small RNAs also induce translational repression of perfectly complementary target mRNAs without, or with only minimal, transcript destabili In contrast to the miRNA 5′ (seed) region, the role of the 3′ region in miRNAtarget recognition is less defined Early evidence arose from reported cases of miRNA repression without perfect pairing in the seed region 13 In those cases, increased pairing in the 3′ region was observed ( Fig 1 B) 31 miRNAs with SNPs in Their Seed Region Are Significantly Enriched in Clusters In total, we identified 1879 SNPs in 1226 (436%) human miRNA seed regions after mapping genetic variation onto human miRNA seed regions based on the genomic coordinates of SNPs in dbSNP human Build 147 and miRNAs in miRBase release 21 (Table S1)
The most critical region for complementarity is the seed region (nucleotides 2–7 from the 5'terminus of the miRNA) 4,7 Aside from the seed region, other criteria have been established that can enhance miRNAmediated repression including complementarity at position 8 and the presence of an adenosine residue opposite the first miRNA nucleotide 8,9 Any polymorphism that interferes with these critical regions will affect miRNA regulation either by disrupting or creating a miRNA The nonseed region of siRNA was found to be subdivided into four domains, in which two nucleotide pairs (positions 13 and 14) were replaceable with cognate deoxyribonucleotides without reducing RNAi activity However, Dcr alone can process dsRNA and premiRNA (11, 24–26), but Dcr appears to form a heterodimer with TRBP or PACTIn miRNA targeting, the seed region (nt g2g7 or g2g8, from the miRNA 5' end) is the primary determinant for targeting efficacy and specificity, with over 80% of miRNAtarget under aCCBYND 40 International license not certified by peer review) is the author/funder, who has granted bioRxiv a license to display the preprint in perpetuity

Is the miRNA seed region always located between the 2 and the 7 nucleotides? Here we show that point mutations in the seed region of miR96, a miRNA expressed in hair cells of the inner ear 8, result in autosomal dominant, progressive hearing loss This is the first study The miRNA sequence can be separated into five functional domains that affect miRNAtarget recognition 5′ anchor (nt 1), seed sequence (nts 2–8), central region (nts 9–12), 3′ supplementary region (nts 13–16), and 3′ tail (nts 17–22) (Wee et al, 12) We anticipated that complementarity to the seed sequence of the cognate miRNA would be a prominent feature in

MiRNA targeting through canonical seed sites (Chen et al, 11) The binding sites for these gene targets, for which the vast majority have been identified in transcript 3'untranslated regions (3'UTRs), contain a canonical base pairing of 6–8 nucleotides to the miRNA 5' seed region It is thought that most miRNAmRNA interactions involve the seed region at the 5′ end of the miRNA The importance of seed sites is supported by experimental evidence, although there is growing interest in interactions mediated by the central region of The significance of seed region (nucleotides 2–8) thermodynamic stability in the process of offtarget effects has been thoroughly explored 17 Our detailed study revealed that the siRNA seed region encompassing nucleotides 2–5 has the highest positive correlation with offtarget effect ( Fig 2 )

Furthermore, additional mRNA pairing to the 3′ region of miRNA, termed as productive seed pairing, can increase the target recognition or it can compensate for the mismatch to the seed (3′ supplementary sites and 3′ compensatory sites, respectively) Base pairing of the miRNA seed region (positions 2–8 from the 5′ end of an miRNA) in animals is critical for target recognition and repression (Bartel, 09;AtoI editing in the miRNA seed region regulates target mRNA selection and silencing efficiency 11 Pages AtoI editing in the miRNA seed region regulates target mRNA selection and silencing efficiency Nucleic acids research, 14 Josephine Galipon Download PDF
