Pheromone binding

WebNov 19, 2024 · In moths, pheromone binding proteins (PBPs), a moth-specific subfamily of OBPs, participate in pheromone reception (Vogt et al., 2015 ). Thus, PBPs are a candidate molecular factor for controlling temporal sensory responses ( Ziegelberger, 1995; Kaissling, 2001, 2009, 2013 ). However, this hypothesis has not been experimentally tested in vivo. WebQueen mandibular pheromone. Queen mandibular pheromone, or QMP, is a honey bee pheromone produced by the queen and fed to her attendants who share it with the rest of the colony to give the colony the sense of belonging to the queen. Newly emerged queens produce very little QMP. By the sixth day they are producing enough to attract drones for ...

WebPheromone-binding proteins (PBPs) are small helical proteins found in sensorial organs, particularly in the antennae, of moth and other insect species. They were proposed to solubilize and carry the hydrophobic pheromonal compounds through the antennal lymph to receptors, participating thus in the peri-receptor events of signal transduction. WebPheromone-binding proteins are small, water-soluble, extracellular proteins of around 130–150 amino acids, with molecular weights of 15–20 kDa, containing six or seven alpha helices that form a conical binding cavity, and six cysteine residues that form three disulfide bonds, maintaining the stability of the three-dimensional structure (Leal et …
