A Putative Lipophilic Stimulant Carrier Protein Commonly Found in the Taste and Olfactory Systems

Abstract: In chemosensory systems, a variety of lipophilic ligand-binding proteins have been found in saliva or nasal mucus. Lipophilic stimulants reach the receptor membrane, carried by these proteins. An acidic 14-kDa protein purified in the blowfly, Phormia regina, belongs to the insect pheromone-binding protein superfamily, but unlike other lipohilic ligand-binding proteins in insect or vertebrate chemosensory systems, it was distributed in both taste and olfactory organs. A similar protein was also isolated in Dros… Show more

“…One out of five OBPs, PBPRP2, is expressed not only in a subset of the olfactory s. coeloconica, but also in taste bristles on the labellum, tarsi, and wings, and in taste pegs on the labellum (Pikielny et al, 1994;Shanbhag et al, 2001). A similarly wide expression range has been described for the related protein CRLBP of the blowfly, Phormia regina (Ozaki et al, 1995). In Drosophila taste bristles, PBPRP2 is expressed in the outer sensillum lymph only and strictly separated from access to the inner lymph space around the dendrite, similar to the situation in s. coeloconica.…”

“…Additional data on the gene products will be required to determine which of these 51 Obp genes encode bona fide OBPs (Steinbrecht et al 1992(Steinbrecht et al , 1995Du and Prestwich 1995;Ozaki et al 1995;Hekmat-Scafe et al 1997;Kim et al 1998;Park et al 2000;Plettner et al 2000).…”

“…We have named another OBP subfamily the CRLBP family (Fig. 4) because it includes an OBP called CRLBP (chemical-sense-related lipophilic-ligand-binding protein) from the fly Phormia regina (P. reg CRLBP; Ozaki et al 1995).…”

“…It is known that chemosensory hairs are filled with a proteinaceous fluid ('receptor lymph') that surrounds the dendrites of the sensory cells up to the pore opening (Foelix and Chu-Wang, 1973;Ozaki et al, 1995;Stürckow, 1967), and globules adhering to the tip of chemosensitive hairs have been described for insects (Slifer et al, 1959) and spiders (Foelix, 1970). As a distally directed flow of this fluid has been shown in the taste hairs of flies (Hodgson, 1968), it could well be that some receptor lymph oozes out when the hair tip is touching the ground and leaves a trail when sliding.…”
