Structural Insights into APOBEC3-Mediated Lentiviral Restriction
Viruses, 2020 Mammals have developed clever adaptive and innate immune defense mechanisms to protect against invading bacterial and viral pathogens. Human innate immunity is continuously evolving to expand the repertoire of restriction factors and one such family of ...

Estimating the Rate of Mutation to a Mutator Phenotype
Axioms, 2023 A mutator is a variant in a population of organisms whose mutation rate is higher than the average mutation rate in the population. For genetic and population dynamics reasons, mutators are produced and survive with much greater frequency than anti-mutators (variants with a lower-than-average mutation rate).

Efficiency of carcinogenesis with and without a mutator mutation [PDF]
Proceedings of the National Academy of Sciences, 2006 Carcinogenesis involves the acquisition of multiple genetic changes altering various cellular phenotypes. These changes occur within the fixed time period of a human lifespan, and mechanisms that accelerate this process are more likely to result in clinical cancers.

Phenotypic diversity in mutagenized population of urdbean (Vigna mungo (L.) Hepper)
Heliyon, 2021 The present study was conducted to assess the extent of induced genetic variability and to determine the inheritance pattern of various yield contributing phenotypic traits in M2 and M3 generations of urdbean following mutagenesis with single and ...

Mutation Spectra and the Neutrality of Mutations [PDF]
Australian Journal of Biological Sciences, 1974 The effect of amino acid replacements on enzyme function was studied in the tJ-galactosidase of Escherichia coli. Mutants possessing 50% or less of normal enzyme activity were isolated and examined. Of 733 amino acid substitutions calculated to have occurred, only 11 reduced tJ-galactosidase activity below 50 %.
