evolution
phylogenetic analysis suggested that OsMSRB5 is a B-type MSR with similar structure to MSRBs of other species, and belongs to 2-Cys MSRB
drug target
MsrB1-dependent reduction of oxidized methionine in proteins may be a regulatory event underlying immunity and inflammatory disease, and a novel target for clinical applications
drug target
the enzyme (MsrB1) may be a therapeutic target with respect to the treatment of hepatocellular carcinoma
malfunction
-
the concomitant absence of both protein isoforms MSRB1 and MSRB2 results in a reduced growth for plants cultivated under high light or low temperature, double mutant lines restored for MSRB2 expression display no phenotype, the absence of plastidial MSRBs is associated with an increased chlorophyll a/b ratio, a reduced content of Lhca1 and Lhcb1 proteins, and an impaired photosynthetic performance
malfunction
-
deficiency in MsrB enzyme reduces the level of Enterococcus faecalis virulence in a systemic and urinary tract infection model
malfunction
loss-of-function studies of MsrB2 using virus-induced gene silencing in pepper plants (cultivar Early Calwonder-30R) result in accelerated cell death from an incompatible bacterial pathogen, Xanthomonas axonopodis pv vesicatoria race 1, and enhanced susceptibility to a compatible bacterial pathogen, virulent Xanthomonas axonopodis pv vesicatoria race 3. Suppression of CaMsrB2 increased the production of reactive oxygen species, which in turn results in the acceleration of cell death via accumulation of reactive oxygen species
malfunction
-
the msrB mutant MSDELTAmsrB exhibits significantly lower intracellular survival than its wild type counterpart and shows no sensitivity to oxidants in vitro. The msrA/B double mutant (MSDELTAmsrA/B) exhibits a phenotype similar to that of msrA mutant in terms of both intracellular survival and sensitivity to oxidants
malfunction
-
cytosolic MsrB7 and MsrB8 knockdown lines are sensitive to oxidative stress
malfunction
-
knockdown of MsrB3A in mammalian cells leads to a significant decrease in the resistance to thapsigargin-induced endoplasmic reticulum (ER) stress, but had no effects on the resistance to either dithiothreitol- or tunicamycin-induced ER stress
malfunction
genetic ablation of MsrB1 doesd not preclude LPS-induced intracellular signaling in macrophages, but results in attenuated induction of antiinflammatory cytokines, such as interleukin (IL)-10 and the IL-1 receptor antagonist
malfunction
MsrB1 knockdown effectively inhibits tumor growth. MsrB1 knockdown reduces hepatocellular carcinoma cell migration and invasion in a transwell assay through inhibition of cytoskeletal rearrangement and spread
malfunction

metabolism
epimastigotes overexpressing the enzyme (MSRB) exhibit inhibition of the metacyclogenesis process
metabolism
reactive oxygen species (ROS) oxidize methionine to methionine sulfoxide (MetSO) and thereby inactivate proteins. Methionine sulfoxide reductase (MSR) enzyme converts MetSO back to the reduced form and thereby detoxifies the effect of ROS
metabolism

physiological function
-
methionine sulfoxide reductase B3 protects from endoplasmic reticulum (ER) stress. Drosophila flies overexpressing human MsrB3A exhibit significantly increased resistance to ER stress induced by dithiothreitol (cell viability is enhanced by 40% and 30% in the treatment of 0.5 and 1 mM dithiothreitol, respectively). These flies also show slightly enhanced resistance to tunicamycin-induced ER stress. The enzyme may be involved in the regulation of ER homeostasis. Overexpression of MsrB3A in mammalian cells increases resistance to dithiothreitol- and thapsigargin-induced endoplasmic reticulum (ER) stresses. However, MsrB3A overexpression has no effect on the resistance to tunicamycin-induced ER stress
physiological function
