Jorgensen, Erik | Caenorhabditis elegans gene unc-25 encodes glutamic acid decarboxylase and is required for synaptic transmission but not synaptic development | The neurotransmitter GABA has been proposed to play a role during nervous system development. We show that the Caenorhabditis elegans gene unc-25 encodes glutamic acid decarboxylase (GAD), the GABA biosynthetic enzyme. unc-25 is expressed specifically in GABAergic neurons. Null mutations in unc-25... | | 1999 |

Jorgensen, Erik | Caenorhabditis elegans unc-49 locus encodes multiple subunits of a heteromultimeric GABA receptor | Ionotropic GABA receptors generally require the products of three subunit genes. By contrast, the GABA receptor needed for locomotion in Caenorhabditis elegans requires only the unc-49 gene. We cloned unc-49 and demonstrated that it possesses an unusual overlapping gene structure. | | 1999 |

Jorgensen, Erik; Schuske, Kimberly R. | CAPS and syntaxin dock dense core vesicles to the plasma membrane in neurons | Docking to the plasma membrane prepares vesicles for rapid release. Here, we describe a mechanism for dense core vesicle docking in neurons. In Caenorhabditis elegons motor neurons, dense core vesicles dock at the plasma membrane but are excluded from active zones at synapses. | | 2008 |
