Thionylation
WebFirstly, methods that allow oxidation of thiols in specific proteins or the global cellular pool to be monitored are discussed. These typically utilise thiol-labelling reagents that add a reporter moiety (e.g. affinity tag, fluorophore, chromophore), in which loss of labelling signifies oxidation. WebThere is augmented lipid peroxidation, protein carbonylation, thionylation and enhanced histone retention in spermatozoa of RPL patients. Differentially expressed proteins in the spermatozoa of RPL patients may contribute towards aberrant embryo development and pregnancy loss.

WebA few years ago, we found that thionylation of Cys 85, the unique cysteine in two identical S100A1 subunits, leads to a drastic increase of the affinity of the protein for calcium. We postulated that the protein activated by thionylation becomes a more efficient calcium signal transmitter. Therefore, we decided to undertake, using nuclear ...
