Voltage-gated Kv1 potassium channels consist of pore-forming alpha subunits and cytoplasmic Kv beta subunits. The latter play diverse roles in modulating the gating, stability, and trafficking of Kv1 channels. The crystallographic structure of the Kv beta2 subunit revealed surprising structural homology with aldo-keto reductases, including a triosephosphate(More)
Huntington's disease (HD) is a progressive neurodegenerative disease caused by a CAG repeat expansion in the coding region of the HD gene. The translated polyglutamine expansion causes the formation of insoluble aggregates in the brains of HD patients and transgenic mouse models. However, the relationship between aggregate formation and neuropathology(More)
Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by an expanded CAG repeat in the HD gene. We reported recently that complexin II, a protein involved in neurotransmitter release, is depleted from both the brains of mice carrying the HD mutation and from the striatum of post mortem HD brains. Here we show that this loss of(More)
Abnormal insoluble ubiqitinated protein aggregates are found in the brains of Huntington's disease (HD) patients and in mice transgenic for the HTT mutation. Here, we describe the earliest stages of visible NII formation in brains of R6/2 mice killed between 2 and 6 weeks of age. We found that huntingtin-positive aggregates formed rapidly (within 24-48(More)
