Nonclassical, Distinct Endocytic Signals Dictate Constitutive And Pkc-Regulated Neurotransmitter Transporter Internalization, Haley Melikian Dec 2004

Nonclassical, Distinct Endocytic Signals Dictate Constitutive And Pkc-Regulated Neurotransmitter Transporter Internalization, Haley Melikian

Haley Melikian

Neurotransmitter transporters are critical for synaptic neurotransmitter inactivation. Transporter inhibitors markedly increase the duration and magnitude of synaptic transmission, underscoring the importance of transporter activity in neurotransmission. Recent studies indicate that membrane trafficking dynamically governs neuronal transporter cell-surface presentation in a protein kinase C-regulated manner, suggesting that transporter trafficking profoundly affects synaptic signaling. However, the molecular architecture coupling neurotransmitter transporters to the endocytic machinery is not defined. Here, we identify nonclassical, distinct endocytic signals in the dopamine transporter (DAT) that are necessary and sufficient to drive constitutive and protein kinase C-regulated DAT internalization. The DAT internalization signal is conserved across …

Single-Channel Properties Of Human Nav1.1 And Mechanism Of Channel Dysfunction In Scn1a-Associated Epilepsy, C. Vanoye, Christoph Lossin, T. H. Rhodes, Alfred L. George

Christoph Lossin, Ph.D.

Mutations in genes encoding neuronal voltage-gated sodium channel subunits have been linked to inherited forms of epilepsy. The majority of mutations (>100) associated with generalized epilepsy with febrile seizures plus (GEFS+) and severe myoclonic epilepsy of infancy (SMEI) occur in SCN1A encoding the NaV1.1 neuronal sodium channel alpha-subunit. Previous studies demonstrated functional heterogeneity among mutant SCN1A channels, revealing a complex relationship between clinical and biophysical phenotypes. To further understand the mechanisms responsible for mutant SCN1A behavior, we performed a comprehensive analysis of the single-channel properties of heterologously expressed recombinant WT-SCN1A channels. Based on these data, we then determined the …
