Recombinant adenovirus encoding enhanced green fluorescent protein-CaV3.1 subunit (Ad-EGFP-CaV3.1) efficiently transduced rat and human islets as well as dispersed islet cells. Ad-EGFP-CaV3.1 transduction reduced phosphorylated FoxO1 in the cytoplasm of rat INS-1E cells, elevated FoxO1 nuclear retention, and decreased syntaxin 1A, SNAP-25, and synaptotagmin III.

Results confirm the idea that T-channels critically support rebound burst firing following periods of membrane hyperpolarization, similar to those that occur during inhibitory synaptic potentials in the ventral tegmental area. Behavioral results indicate that deletion of CaV3.1 channels disrupts the hyperlocomotion.
Title: Ca(V)3.1 isoform of T-type calcium channels supports excitability of rat and mouse ventral tegmental area neurons.
Results show that the decrease in Cav3.1 channel expression and Ca2+ current component that they carry in thalamocortical relay neurons serves as a protective measure against early onset of spike-wave discharges and absence seizures

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
