Akt2 regulates expression of the actin-bundling protein palladin.

abstract：:The tetracycline-controlled transcription system has become one of the most potent systems for experimental manipulations of transcription levels in vivo. Here we report on rtTA variants, which were generated by combining the existing positively regulated Tet repressor domains of rtTA and rtTA-M2 with a modified and m...

Among prokaryotes, the influence of these factors is different if the genome is skewed towards AT or GC, since in AT-rich organisms translational selection is absent. On the other hand, in AT-rich unicellular eukaryotes the tw...
