Sequence Information

  • Sequence:  NPTNLH
  • Length:  6
  • Propeptide:  NPTNLH
  • Signal peptide:  NA
  • Modification:  NA
  • Glycosylation:  NA
  • Mutagenesis:  NA

Activity

  • Function:  Has an oostatic activity. Inhibits trypsin biosynthesis in the midgut which indirectly reduces the vitellogenin concentration in the hemolymph resulting in inhibition of oocyte development.
