15 Mar 2016 | Ample literature evidences confirm the suitability of this protein as a good target. |
This mutant protein is more efficiently GPI-modified than any mutant AChE tested thus far. | |
The mutant protein appears to have a dominant negative effect, which could be due to it dimerising with the wild-type protein and inhibiting its activity, thus further reducing the levels of functional protein. | |
Increasing gene expression restored mutant fitness to varying degrees, demonstrating that the fitness disadvantage of synonymous mutants arose from a lack of beneficial protein rather than costs of protein production. | |
10 Citations | The high level of success shows that relatively "simple" computational methods can in some cases predict the behavior of mutant proteins with good reliability. |
19 Citations | In some cases, therefore, it is possible that the mutant protein exerts a dominant negative effect. |
In the case of interference, increased production of the wild-type protein may be therapeutic, but in the case of toxicity, suppression of the mutant protein may also be needed. | |
32 Citations | Cells of the mutant are viable, showing that the protein is dispensable for growth, but grow slower and have thickened cell walls. |
21 Citations | Although this scheme requires no knowledge of the structure of a mutant protein, it is useful in predicting the activities of mutants. |
The swapped mutant was destabilized by 3 kcal/mol per gene V protein dimer relative to the wild-type protein, demonstrating that factors other than hydrophobicity must make substantial contributions to the effects of mutations on the stability of the protein. |

What is the impact of five missense mutations on the function of a protein?5 answersFive missense mutations in different proteins have been studied for their impact on protein function. The mutations in OPN3, desmoplakin, SMAD4, MERS-CoV S protein, and cytosolic proteins were found to have deleterious effects on protein structure and function. In OPN3, the p. I51T variant failed to effectively dock with 11‐cis‐retinal, leading to a loss of function. For desmoplakin, mutations rendered PRD proteins insoluble and compromised cytoskeletal linkages. In SMAD4, mutations resulted in deformed and unstable protein structures, affecting protein-ligand interactions. Mutations in MERS-CoV S protein affected protein stability and binding affinity with the DPP4 receptor. Additionally, SNVs in cytosolic proteins altered peroxisomal targeting signals, impacting protein import. These findings highlight the diverse ways missense mutations can disrupt protein function, providing insights for potential therapeutic interventions.
How does mutation testing work?5 answersMutation testing is a fault-based testing technique that evaluates the effectiveness of a test suite in detecting faults. It involves seeding faults into the program under test and then writing tests to reveal these faults. The goal is to create tests that can detect a large number of faults, including those that couple with the seeded faults. Several approaches have been proposed to improve the efficiency of mutation testing. One approach is to automate the process using tools like Mutta, which can automate the mutation testing process for web applications. Another approach is to scale mutation testing by using distributed systems and load distribution algorithms, which can significantly reduce the computational cost. Additionally, there are efforts to adapt mutation testing for deep learning models, such as Probabilistic Mutation Testing (PMT), which addresses the stochasticity inherent in training deep learning models and allows for more consistent and informed decisions on mutations.
Can mutations be inherited?5 answersMutations can be inherited from previous generations. Most gene variants in an individual's genome are not new mutations but have been passed down through generations. In the case of genetic diseases caused by a single mutation in one gene, such as cystic fibrosis, haemophilia, and achondroplasia, the inheritance of the abnormal gene variant follows simple Mendelian rules. Studies have shown that point mutations in male germ cells can be transmitted to the next generation without severe selection. In the context of upper tract urothelial carcinoma (UTUC), germline pathogenic/likely pathogenic mutations have been identified and found to significantly increase UTUC risk in Chinese populations. In the case of gynecological cancers, a genetic predisposition can contribute to up to 10% of cases, and risk-reducing surgery may be offered to high-risk individuals. In prostate cancer, germline pathogenic variants have been underestimated, and enhanced family history screening and genetic testing have been used to identify these variants.
Is there mutation load in bacteria?5 answersMutation load in bacteria refers to the accumulation of deleterious mutations in a population. Studies have shown that bacteria can exhibit mutation rate polymorphism, ranging from wild-type levels to significantly higher rates. Despite the presence of large numbers of deleterious mutations, beneficial mutations do arise but often do not reach fixation over long periods of time. This suggests that the dynamics of beneficial mutations in bacteria are not solely driven by constant positive selection, but rather by other evolutionary mechanisms such as negative frequency-dependent or temporally fluctuating selection. The low mutational load observed in bacteria is consistent with the pattern of genetic polymorphism observed in metagenomics studies of the human gut microbiota. Therefore, it can be concluded that while bacteria do experience mutation load, the presence of beneficial mutations and other evolutionary mechanisms contribute to the maintenance of genetic diversity and the long-term survival of bacterial populations.
