The solution structure of trypsin modulating oostatic factor (TMOF), a decapeptide (H-YDPAPPPPPP-OH) hormone that signals the termination of trypsin-like biosynthesis in mosquito midgut epithelial cells, was determined by 2-D 1H nuclear magnetic resonance spectroscopy and molecular modeling. The peptide forms a rod-shaped left-handed helix about 30 A long. No evidence was found to support a poly-L-proline beta-turn model. Hydrophobic contacts between the rings of tyrosine 1 and proline 3 may… 
Trypsin-modulating oostatic factor: a potential new larvicide for mosquito control
TLDR
TMOF can be used as a new biorational insecticide against mosquito larvae and cause high larval mortality, according to the results.
The Ribosome Is the Ultimate Receptor for Trypsin Modulating Oostatic Factor (TMOF)
TLDR
Results suggest that the ribosome is the ultimate targeted receptor of AeaTMOF, a mosquito decapeptide that controls trypsin biosynthesis in female and larval mosquitoes.
Complete1H NMR assignments of synthetic glycopeptides from the carbohydrate-protein linkage region of serglycins
TLDR
Preliminary analysis of the NMR data suggests folded structures for the glycopeptides in the serglycin proteoglycans.
Characterization and localization of mosquito‐gut receptors for trypsin modulating oostatic factor using a complementary peptide and immunocytochemistry
TLDR
The results suggest that TMOF regulates trypsin biosynthesis by binding to specific receptor sites that are located on the mosquito gut, and that this receptor can be studied using a complementary peptide approach.
Cloning and Characterization of Aedes aegypti Trypsin Modulating Oostatic Factor (TMOF) Gut Receptor
TLDR
A 3D modeling of the receptor indicates that the receptor has ATP binding sites and TMOF transport into recombinant E. coli cells is inhibited with ATPase inhibitors Na Arsenate and Na Azide.
Biosynthesis and Control of Mosquito Gut Proteases
TLDR
Genetic engineering and expression of TMOF in bacteria, yeast and algae is emerging as a potential future larval control of mosquitoes in the field and is controlled by a decapeptide hormone; trypsin modulating oostatic factor (TMOF) that is secreted by the mosquito ovary.
CLONING AND EXPRESSING TRYPSIN MODULATING OOSTATIC FACTOR IN Chlorella desiccata TO CONTROL MOSQUITO LARVAE.
The insect peptide hormone trypsin modulating oostatic factor (TMOF), a decapeptide that is synthesized by the mosquito ovary and controls the translation of the gut's trypsin mRNA was cloned and
Effect of ace inhibitors and TMOF on growth, development, and trypsin activity of larval Spodoptera littoralis.
TLDR
The effects of ACE inhibitors on larval growth in the cotton leafworm Spodoptera littoralis are reported and ACE plays an important role in larvalgrowth and development.
