About Dr. Featherstone's Research

The Featherstone lab identifies and provides initial characterization of genes required for nervous system development. Specifically, we look for things that control expression and/or localization of glutamate receptors, which mediate most fast cell-to-cell communication in the brain.

Our work uses fruit flies, mice, and a variety of powerful techniques, including molecular genetics and transgenics (to discover and manipulate proteins at the most basic level), recombinant nucleotide biology and gene expression assays (to clone genes and precisely measure gene expression), immunohistochemistry, confocal and electron microscopy (to determine where and when protein is localized), voltage-clamp synaptic electrophysiology (to measure the functional properties of receptors and overall synaptic efficacy), and sophisticated behavioral assays (to confirm that the molecular changes we see have behavioral significance). We have named and studied several previously uncharacterized genes, and routinely produce novel community reagents such as antibodies and mutants.

More information is available via our lab web page.
