[https://www.uniprot.org/uniprot/D7L1_AEDAE D7L1_AEDAE] Modulates blood feeding of female mosquitoes on vertebrate species by binding and sequestering different mediators involved in the host response, such as biogenic amines and eicosanoids (PubMed:32799410, PubMed:37909749). Binds serotonin, histamine, leukotriene B4, leukotriene C4, leukotriene D4, leukotriene E4, adrenaline and noradrenaline (PubMed:16301315, PubMed:19234127, PubMed:32799410). Does not bind tryptamine and U-46619, a stable analog of thromboxane A2 (PubMed:19234127, PubMed:32799410). Exhibits vasodilating activity (PubMed:32799410). Inhibits agonist-induced platelet aggregation but not blood clotting (PubMed:32799410). Inhibits noradrenaline-induced smooth muscle contraction (PubMed:16301315). Promotes an influx of host neutrophils at the inoculation site (PubMed:38378891).<ref>PMID:16301315</ref> <ref>PMID:19234127</ref> <ref>PMID:32799410</ref> <ref>PMID:37909749</ref> <ref>PMID:38378891</ref> (Microbial infection) Probably promotes Plasmodium gallinaceum oocyst development in mosquito midgut.<ref>PMID:37909749</ref> (Microbial infection) Exhibits antiviral activity against dengue virus type 2 probably through a direct interaction with dengue virus virions.<ref>PMID:27632170</ref>

== Publication Abstract from PubMed ==

The mosquito D7 salivary proteins are encoded by a multigene family related to the arthropod odorant-binding protein (OBP) superfamily. Forms having either one or two OBP domains are found in mosquito saliva. Four single-domain and one two-domain D7 proteins from Anopheles gambiae and Aedes aegypti (AeD7), respectively, were shown to bind biogenic amines with high affinity and with a stoichiometry of one ligand per protein molecule. Sequence comparisons indicated that only the C-terminal domain of AeD7 is homologous to the single-domain proteins from A. gambiae, suggesting that the N-terminal domain may bind a different class of ligands. Here, we describe the 3D structure of AeD7 and examine the ligand-binding characteristics of the N- and C-terminal domains. Isothermal titration calorimetry and ligand complex crystal structures show that the N-terminal domain binds cysteinyl leukotrienes (cysLTs) with high affinities (50-60 nM) whereas the C-terminal domain binds biogenic amines. The lipid chain of the cysLT binds in a hydrophobic pocket of the N-terminal domain, whereas binding of norepinephrine leads to an ordering of the C-terminal portion of the C-terminal domain into an alpha-helix that, along with rotations of Arg-176 and Glu-268 side chains, acts to bury the bound ligand.
