This plasmid is identical to HIC except that it has a point mutation which introduces a stop codon at amino acid 164, immediately before the I-mfa domain.
The A66W mutation, which introduces a bulky hydrophobic side chain and induces massive vesiculation of liposomes in vitro, strongly impeded eye development, even in presence of the endogenous endoA gene.
It is comparable to the talpid 3 chicken loss-of-function mutation which introduces a frameshift in the orthologous region.
The most obvious surface distortion, whether statically or dynamically derived, is contributed by the V516I mutation, which introduces a methyl group into the active site cavity (Supplementary Figure S5).
The beneficial effect of complementation may be enhanced by efficient mtDNA replication, as provided by CR mutations which introduce alternative replication sites.
It is estimated that approximately one-third of all inherited disorders and some forms of cancer are caused by nonsense or frame shift mutations, which introduce premature translation termination codons (PTC) into the reading frame of mRNAs.
This action of antibiotics such as gentamicin can be used for therapeutic purposes in genetic diseases that arise from point mutations which introduce premature stop codons (UAA, UAG, UGA) into coding sequences [ 6, 7].
If so, we expect cancer transcripts to: (A) have a higher incidence of nonsense or frameshift mutations which introduce a premature translation termination codons to mRNAs resulting in truncated proteins or more often rendering them vulnerable to nonsense-mediated decay (13, 14).
In this study, we show the first reported case of IAV adaptation to a new host by the selection of a mutation, NS1 D125G(GAT→GGT), which introduced a new splice site into the NS gene, hence producing the novel NS3 protein by alternative splicing.
The construct Luc+125b mutated MRE, which introduced some mutations in the seed region of miR-125b MRE, was synthesised by ligating the mutation MRE fragment of miR-125b into the psiCheck2 vector as described previously (Le et al, 2009b).
