Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels mediate the hyperpolarization-activated current I(h) and thus play important roles in the regulation of brain excitability. The subcellular distribution pattern of the HCN channels influences the effects that they exert on the properties and activity of neurons. However, little is known(More)
Prokaryotic and eukaryotic cells incorporate the unusual amino acid selenocysteine at a UGA codon, which conventionally serves as a termination signal. Translation of eukaryotic selenoprotein mRNA requires a nucleotide selenocysteine insertion sequence in the 3'-untranslated region. We report the molecular cloning of the binding protein that recognizes the(More)
Prokaryotic and eukaryotic cells cotranslationally incorporate the unusual amino acid selenocysteine at a UGA codon, which conventionally serves as a termination signal. Translation of selenoprotein gene transcripts in eukaryotes depends upon a "selenocysteine insertion sequence" in the 3'-untranslated region. We have previously shown that DNA-binding(More)
Type II iodothyronine deiodinase is a short-lived, membrane-bound enzyme found in rat brain, brown adipose tissue, and cAMP-stimulated astrocytes. Recently, a full-length complementary DNA (cDNA) encoding a 30-kDa, type II-like selenodeiodinase was cloned from frog, and a homologous partial cDNA (rBAT 1.1), containing two in-frame selenocysteine codons(More)
