Proteasomal activity in isolated monocytes from subjects with different variants of large multifunctional proteases genes - LMP2 (Arg60 His allelic polymorphism) and LMP7 (Lys145 Gln allelic polymorphism) was determined. Trypsin-like activity of proteasome was 1.6-times (P=0.19) higher at Arg/Arg genotype comparing to His/His genotype, and 2-fold lower than at Arg/His genotype. The highest chymotrypsin-like activity of proteasome was observed in heterozygotes (on 29.7% higher comparing to Arg/Arg geno- type, Р=0.43) and lowest in homozygotes His/His (on 29.7% less comparing to Arg/Arg genotype, Р=0.40). Level of RNA expression in isolated monocytes detetermined by use of RT- PCR did not differed significantly in subjects with different genotypes. Data obtained indicate that LMP2 allelic poly- morphism impact peptidase activity of immunoproteasome.
