The cDNAs encode a seven transmembrane domain protein (DTKR) of 519 amino acids with 40–48% amino acid identity to mammalian tachykinin receptors within transmembrane regions. Xenopus oocytes injected with DTKR cRNAs showed selective responses to vertebrate substance P, its agonists and not to other vertebrate tachykinin peptides. These responses were eliminated by treatment of oocytes with pertussis toxin. In the adult fly, Northern and PCR analysis demonstrated preferential expression of DTKR in the head; in situ hybridization indicated that DTKR is accumulated in the cell bodies of neurons in the adult CNS. The levels of DTKR transcript are regulated during development. Northern and PCR amplification analysis showed that while DTKR transcripts are present at all stages, high levels of expression occur in later stages of embryogenesis (starting at 10–14 h), coinciding with the beginning of major periods of neural development. Whole mount embryo in situ hybridization demonstrated that DTKR is expressed at these later stages of embryogenesis (11–15 h) in the brain and in a specific subset of neurons in each neuromere of the developing ventral ganglion. The gene encoding DTKR was mapped by in situ hybridization to a single location at 99D on the right arm of chromosome 3. These observations demonstrate that the tachykinin family of peptide transmitters and their receptors represent an evolutionarily ancient form of cellular communication within the nervous system.(ABSTRACT TRUNCATED AT 250 WORDS) Previous ArticleNext Article Volume 10Issue 111 November 1991In this issue RelatedDetailsLoading ...
