Caenorhabditis elegans Flamingo Cadherin fmi-1 Regulates GABAergic Neuronal Development
(Society for Neuroscience, 2012-03-21)In a genetic screen for regulators of synaptic morphology, we identified the single Caenorhabditis elegans flamingo-like cadherin fmi-1. The fmi-1 mutants exhibit defective axon pathfinding, reduced synapse number, aberrant ... -
Long-distance potentials: An approach to the multiple-minima problem in ligand-receptor interaction
(Oxford University Press, 1996-01-01)The multiple-minima problem is a classical problem in molecular structure prediction. For ligand-receptor systems, a possible direction to alleviate this major obstacle is to simplify the objective function (intermolecular ... -
