Identification of cDNAs encoding allatotropin and allatotropin-like peptides from the silkworm, Bombyx mori

► The cDNAs encoding allatotropin (AT) and allatotropin-like peptides (ATLPs) were isolated from the silkworm, Bombyx mori. ► Splice variants of AT and ATLPs were expressed in the central nervous system with differing expression patterns in each ganglion. ► Injection of AT and ATLPs into B. mori larvae increased the latency to feed, indicating the contribution of AT and ATLP to feeding behavior.
