Solution structure and functional characterization of SGTx1, a modifier of Kv2.1 channel gating.
SGTx1 is a peptide toxin isolated from the venom of the spider Scodra griseipes that has been shown to inhibit outward K(+) currents in rat cerebellar granule neurons. Although its amino acid… Expand
New details from the complete life cycle of the red-tide dinoflagellate Noctiluca scintillans (Ehrenberg) McCartney.
Noctilucid protozoans are among the dinoflagellates that cause red tides. Sexual reproduction may occur in this group, as they sometimes undergo gametogenesis. However, the life cycle, in particular… Expand
Total DNA transcription in vitro: a procedure to detect highly repetitive and transcribable sequences with tRNA-like structures.
Total DNAs from various animals were transcribed in vitro in a HeLa cell extract, and it was found that one to several discrete RNAs were transcribed by RNA polymerase III. With tortoise (Geoclemys… Expand
Role of apoptosis-inducing factor (AIF) in programmed nuclear death during conjugation in Tetrahymena thermophila
BackgroundProgrammed nuclear death (PND), which is also referred to as nuclear apoptosis, is a remarkable process that occurs in ciliates during sexual reproduction (conjugation). In Tetrahymena… Expand
Gigantic macroautophagy in programmed nuclear death of Tetrahymena thermophila
Programmed nuclear death (PND) in Tetrahymena is a unique process during conjugation, in which only the parental macronucleus is degraded and then eliminated from the progeny cytoplasm, but other… Expand
Phylogenetic analyses of the dinoflagellate Noctiluca scintillans based on beta-tubulin and Hsp90 genes.
The noctilucid dinoflagellate Noctiluca scintillans is an unarmed heterotrophic protist that inhabits the world's oceans and is sometimes responsible for harmful red tides. The phylogenetic position… Expand

Actin is ubiquitous in eukaryotes, nevertheless its existence has not yet been clearly proven in Tetrahymena. Here we report the cloning and sequencing of an actin gene from the genomic library of… Expand
Caspase-like activity in programmed nuclear death during conjugation of Tetrahymena thermophila
AbstractApoptosis, or programmed cell death, is common in a variety of eucaryotes, from unicellular protozoa to vertebrates. The ciliated protozoan Tetrahymena thermophila has a unique apoptosis-like… Expand
A possible role of mitochondria in the apoptotic‐like programmed nuclear death of Tetrahymena thermophila
The ciliated protozoan Tetrahymena has a unique apoptosis‐like process, which is called programmed nuclear death (PND). During conjugation, the new germinal micro‐ and somatic macro‐nuclei… Expand
A highly repetitive and transcribable sequence in the tortoise genome is probably a retroposon.
On in vitro transcription of total genomic DNA of the tortoise (Geoclemys reevessi), a discrete-sized RNA of 6.5S was obtained that represented a highly repetitive and transcribable sequence in the… Expand
