Jason H. Brickner Cell biology of transcription

Research Interests

The genome is spatially organized within the nucleus. The position of individual genes is dynamically regulated and impacts their expression.

The Brickner lab studies the molecular mechanisms that control gene positioning in budding yeast and human cells.  Current work in the lab is focused on three areas: 1) defining the molecular mechanisms by which transcription factors target genes to different subnuclear environments, 2) how gene positioning is integrated with interchromosomal clustering to influence the spatial organization of the genome as a whole and 3) exploring how gene positioning impacts chromatin structure, transcription and epigenetic regulation.  We employ molecular genetics, biochemistry, live cell microscopy and genomics to address these questions.
