DNA polymerase iota (Pol ι) which has some peculiar features and is characterized by an extremely error prone DNA synthesis, belongs to the group of enzymes preferentially activated by Mn2+ instead of Mg2+. In this work, using misGvA method (misincorporation of “G” versus “A”, method of Gening) we studied the effect of Mn2+ on DNA synthesis in cell extracts(More)
Human DNA polymerase iota (Pol ι) is a Y-family DNA polymerase with unusual biochemical properties and not fully understood functions. Pol ι preferentially incorporates dGTP opposite template thymine. This property can be used to monitor Pol ι activity in the presence of other DNA polymerases, e.g. in cell extracts of tissues and tumors. We have now(More)
Over the last few years, in vitro models, based on patient-derived induced pluripotent stem cells (iPSCs), have received considerable attention for modeling different neurodegenerative disorders. Using this model, we analyzed transcription of 15 tripartite motif (trim) genes in iPSCs, derived from the different groups: Parkinson’s disease (PD) patients(More)
Using a modified radiolabeled primer extension method (we named this modification misGvA— " misincorporation of G versus A ") we have investigated the DNA synthesis and repair at early and late stages of development of loach Misgurnus fossilis. The misincorporation activity of DNA polymerase iota (Pol ι) in wild-type loach could not be detected by this(More)
