A Novel Test System for Genotyping rs43703016 Single-nucleotide Substitutions in the Bovine CSN3 Gene

Svetlana Kovalchuk, Arina Tagmazyan & Eugene Klimov · Annual Research & Review in Biology · 2019

Aims: Caseins are among the main milk proteins that determine many of its properties. Bovine kappa-casein (CSN3) is associated with the qualitative composition of milk, as well as with the quality of cheese obtained from this milk. The rs43703016 single-nucleotide substitution (g...

Frequencies of Genotypes and Alleles of the K232A Substitution in the DGAT1 Gene in Four Cattle Breeds of Russian Selection

Eugene Klimov, Anna Arkhipova & Svetlana Kovalchuk · Annual Research & Review in Biology · 2018

The enzyme DGAT1 is involved in the synthesis of triglycerides. The most well-known polymorphic variant of the DGAT1 gene is substitution of lysine with alanine at position 232 of the protein (K232A). The 232K allele is associated with increased enzyme activity and a higher conte...

The Search for a Receptor for Cell Infection by Bovine Leukemia Virus: Data Mining and Signaling Pathways Analysis

Eugene Klimov, Anna Shevtsova & Svetlana Kovalchuk · Annual Research & Review in Biology · 2018

The bovine leukaemia virus (BLV) is widely spread all over the world. Currently, treatment of leukaemia-infected animals is not carried out. Not all virus carriers become ill with leukaemia. The existing genetic resistance to the disease is due to the presence of alleles of resis...
