The KCNQ gene family comprises voltage-gated potassium channels expressed in epithelial tissues (KCNQ1, KCNQ5), inner ear structures (KCNQ1, KCNQ4) and the brain (KCNQ2-5). KCNQ4 is expressed in inner and outer hair cells of the inner ear where it determines electrical excitability. Accordingly, loss of function mutations of the KCNQ4 gene cause hearing(More)
Previous studies revealed a linkage of the kainate receptor GluR6 with autism, a pervasive developmental disorder. Mutational screening in autistic patients disclosed the amino acid exchange M836I in a highly conserved domain of the cytoplasmic C-terminal region of GluR6. Here, we show that this mutation leads to GluR6 gain-of-function. By using the(More)
The serum- and glucocorticoid-inducible kinase isoform 3 (SGK3) and stargazin have both been shown to enhance the synaptic expression level of GluR1. The present study was performed to elucidate whether SGK3 and stargazin interact or are effective through different pathways in the regulation of GluR1. Proteins were expressed in Xenopus oocytes by injection(More)
