    basic FUNCTION
  • reducing insulin disulfide bonds in the presence of NADPH and thioredoxin reductase
  • important factor in regulating critical steps of spermiogenesis
  • may be governing the stabilization (by disulfide cross-linking) of the different structures in the developing tail of spermatids and spermatozoa
  • TXNDC2 and NME8, retain association with the spermatozoa after spermiation and potentially play an important role in regulating the redox status of the mature gamete
  • sperm-specific thioredoxins, TXNDC2 and NME8, are critically important in protecting these cells against the increases in oxidative stress associated with paternal age
  • CELLULAR PROCESS cell life, differentiation
