WebJan 1, 2011 · Three isoforms of Gpx4 proteins are generated from the Gpx 4 gene in mammals: a long form (lGpx4), a short form (sGpx4), and a nuclear form (nGpx4). The N-terminal of nGpx4 protein is encoded by an alternative first exon called exon Ib, and nGpx4 protein is mainly expressed in sperm nuclei [ 41 ]. WebPhospholipid hydroperoxide glutathione peroxidase (GPx4) is a selenocysteine-containing enzyme, and three different isoforms (cytosolic, mitochondrial, and nuclear) originate from the GPx4 gene. Homozygous GPx4-deficient mice die in utero at midgestation, since they fail to initiate gastrulation and do not develop embryonic cavities. WebAmong the various isoforms, the selenoprotein GPX4 is the only one which—with its cofactor GSH—directly detoxifies lipid hydroperoxides by promoting the reaction to lipid alcohols . The synthesis of GSH is dependent on the availability of cysteine, which is derived from its precursor molecule cystine. fly us manage my booking
