Biochemistry and molecular biology of receptors for biogenic amines in locusts.

The biochemistry and molecular biology of biogenic amines and their metabotropic receptors in insects, with a focus on locusts, is reviewed. These compounds are known to be responsible for the control of a huge variety of different behaviours. Receptors for these amines usually belong to the class of G-protein coupled receptors (GPCR) and transmit all known functions of these compounds. The physiological significance of biogenic amine neurotransmission in insects, especially in locusts is briefly summarised. Regarding the corresponding receptors, their pharmacological features and the molecular properties are described in detail. Copyright 2002 Wiley-Liss, Inc.
