Coexpression of rat P2X2 and P2X6 subunits in Xenopus oocytes.
Transcripts for P2X(2) and P2X(6) subunits are present in rat CNS and frequently colocalize in the same brainstem nuclei. When rat P2X(2) (rP2X(2)) and rat P2X(6) (rP2X(6)) receptors were expressed individually in Xenopus oocytes and studied under voltage-clamp conditions, only homomeric rP2X(2) receptors were fully functional and gave rise to large inward currents (2-3 microA) to extracellular...
متن کاملXenopus Oocytes
lnjection of Xenopus oocytes with poly(A)+ mRNA isolated from different plants (maize, cucumber, and squash) results in the appearance of a voltageand time'dependent, potassium-selective, outward current that is similar to the outwardrectifying potassium current recorded in many higher plant cells. Maize shoots were found to be especially enriched in mRNA encoding such activity. A cDNA library ...
متن کاملXenopus oocytes
The induction of amphibian oocyte maturation with progesterone as well as the activation of sea urchin eggs at the time of fertilization result in increased protein synthesis. The increase in both cases involves the recruitment of maternal mRNA onto polysomes. Further, it has been reported that sea urchin eggs, like full-grown Xenopus oocytes, contain no spare translational capacity based on th...
متن کاملCa channels induced in Xenopus oocytes by rat brain mRNA.
RNA was isolated from brains of 16-d-old rats and poly(A) samples were injected into stage V and VI oocytes. After allowing 2-5 d for expression, most oocytes were exposed to medium in which the K had been replaced by Cs for 24 hr prior to recording. Ba currents were usually measured in Cl-free Ba-methanesulfonate saline. IBa in noninjected oocytes was often undetectable, but ranged up to 50 nA...
متن کاملActin in Xenopus oocytes
It has been found that a high-speed supernatant fraction from Xenopus oocytes extracted in the cold will form a clear, solid gel upon warming. Gel formation occurs within 60 min at 18 degrees-40 degrees C, and is, at least initially, temperature reversible. Gelation is strictly dependent upon the addition of sucrose to the extraction medium. When isolated in the presence of ATP, the gel consist...
