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 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

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
