Dr. N. Koltovaya graduated Moscow Physical Institute and received her Diploma and PhD under the direction of Dr Alexandr B. Devin at the Laboratory of Genetics of Somatic Cells (Leader- N.I. Shapiro) in Institute of Molecular Genetics RAN, Moscow. She works at JINR from 1979 and now she is Leader of Group of Radiogenetics of Yeast. Her pioneering work over many years in pursuit of the genetic control of different genetic structures (chromosomes, mitochondrial genome and recombinant plasmids) and connection with control of radiosensitivity of yeast cells.


Research interest

She is studying the genetic control of stability of different genetic systems in yeast cells. They are characterizing several genes designated as SRM (spontaneous of rho- mutability), which mediate the maintenance of mitochondrial genome, chromosomes and plasmids. 3 genes were cloning and sequencing and showed the SRM5, SRM8 and SRM12 genes to be identical to CDC28, NET1 and HFI1, respectively. These genes encode constituents of multiprotein complexes that regulate cell cycle progression and transcription. Now she investigates its role in checkpoint control.
