The role of activating protein 1 in the transcriptional regulation of the human FCGR2B promoter mediated by the -343 G -> C polymorphism associated with systemic lupus erythematosus.

Abstract excerpt

The inhibitory receptor FcgammaRIIb is a negative regulator of antibody production and inflammatory responses. The -343 G --> C polymorphism in the human FCGR2B promoter is associated with systemic lupus erythematosus. The -343 C mutant promoter has decreased transcriptional activity. In the present study, we show that the transcriptional change correlates with quantitative differences in the interaction of the...
