Gene encoding the 1a subunit of the major calcium channel of the cerebellum. Our group has found that this mutation, which is a type called an expanded polyglutamine (polyq) tract that is seen in other neurodegenerative diseases, alters the function of calcium channel protein in at least two fashions. First, the expanded polyq tract makes the calcium channel leaky, potentially leading to calcium overload of purkinje cells and activation of degenerative pathways as is seen in that disorder. More importantly, we have discovered that the c terminal portion of the calcium channel that contains the polyq tract is actually a form of nuclear signaling protein that is cleaved from the channel and transported to the nucleus. viagra buy online in uk Mice lacking this channel or the c terminus develop poorly, and die with dystonia, seizures and ataxia. Mice expressing the c terminus alone survive. C terminal calcium channel proteins that contain the expanded polyq tract are toxic to neurons and appear to cause damage by disturbing the dna repair pathways. We are now delineating the normal and pathological actions of the calcium channel c terminus using biochemical cellular and genetic approaches. cheap viagra online   back to top select publications vohra, b.
