The dissociable sigma subunit of bacterial RNA polymerase is required for the promoter-specific initiation of transcription. When bound to RNA polymerase, sigma makes sequence-specific promoter contacts and plays a crucial role in DNA melting. In isolation, however, sigma lacks significant
We identified a novel azaindole derivative, L-750,667, that has high affinity (Ki = 0.51 nM) and >2000-fold selectivity for D4 dopamine receptors compared with its activity at D2 and D3 dopamine receptors. L-750,667 had little affinity for rat D1/D5 dopamine

The transcriptomes of Salmonella enterica serovar Typhimurium SL1344 lacking a functional ramA or ramR or with plasmid-mediated high-level overexpression of ramA were compared to those of the wild-type parental strain. Inactivation of ramA led to increased expression of 14 SPI-1
The molecular determinants that govern selective ligand binding to the rat D(4) dopamine receptor were investigated by substituting D(2) dopamine receptor sequences into a D(4) dopamine receptor background. The resulting mutant D(4) dopamine receptors were then screened with a panel
3-((4-(4-Chlorophenyl)piperazin-1-yl)-methyl)-1H-pyrrolo-2,3-b-pyridine: an antagonist with high affinity and selectivity for the human dopamine D4 receptor.
