Duplication of the escape-response neural pathway by mutation of the Bithorax-complex

Article Abstract:

Researchers have determined some of the segmental identities of neuromuscular elements in the transformed metathorax of the bithorax-complex mutant abx bx3 pbx/Df (3R) P2, and identified the existence of a duplicated neural passage for the escape-jump reaction inside that segment. A motor neuron was not always adequate to stimulate or influence the development of its target muscle.

Proteins of the CNR family are multiple receptors for Reelin

Article Abstract:

Results demonstrate that Cadherin-related neuronal proteins (CNR) function as multiple receptors for signal transduction mediated by Reelin in the central nervous system. Data further point out that the number of CNR genes containing Reelin-binding domains vary across terrestrial vertebrates.
