The Binding of Juvenile Hormone to Larval Epidermis: Influence of Carrier Protein from the Hemolymph of Plodia interpunctella

Biology of the Integument

“…These proteins are thought to protect JH against non-specific esterases (Ferkovich et al 1976). These proteins are thought to protect JH against non-specific esterases (Ferkovich et al 1976).…”

Regulation of Hemoglobin Production in Chironomus Thummi by Juvenile Hormone and Ecdysterone

“…The biosynthesis and release of JH is controlled by the neurosecretory and neurohemal activity of corpora aliata (Gilbert and King, 1973;Williams, 1976). The final concentration of JH is then modulated by the presence of carrier proteins, a possible means of protection against degradation (Ferkovich et al, 1976;Ferkovich et al, 1977;Slade and Zibitt, 1972). The lipoidal JH is transported in the aqueous hemolymph by a hydrophilic carrier, since the known titers of hemolymph JH exceed the solubility of the hormone in water.…”

“…The lipoidal JH is transported in the aqueous hemolymph by a hydrophilic carrier, since the known titers of hemolymph JH exceed the solubility of the hormone in water. Carrier proteins were identified in the hemolymph of Locusta (Emmerich and Kartmam, 1973) , Manduca , Plodia (Ferkovich et al, 1976),…”

“…JH binds to various subcellular fractions of Plodia epidermal cells, such as mitochondrial, nuclear and microsomal fractions. The specific receptor site may be a ribonucleoprotein (Ferkovich et al, 1976).…”
