Transcriptional expression of a putative tachykinin-like peptide receptor gene from stable fly.

STKR is a 4118 bp clone from a stable fly, Stomoxys calcitrans, cDNA library which encodes a protein with significant amino acid identity to tachykinin-like peptide receptors. Ribonuclease protection assays and RT-PCR were utilized to examine the transcriptional expression of STKR from various life stages of the stable fly. STKR expression was detectable in all stages, but was most abundant in isolated adult fly gut and lowest in developing embryos.
