Synapses Making New Ties
Neurons communicate with one another through specialized junctions called synapses that are so robust that they survive homogenization. Although several cell-surface receptor-ligand pairs have been proposed to participate in forming and maintaining synapses, one of the best families of candidates--the immunoglobulin-domain proteins--have only been found in invertebrates. Biederer et al. report that IGSF4 is a homophilic protein that can induce the formation of fully functional glutamatergic synapses when cotransfected into nonneural, vertebrate human embryonic kidney (HEK) cells along with glutamate receptors.
