Scientific Interest(s):

Dr. Douglas Black's lab is interested in the regulation of pre-mRNA splicing in neurons and the biochemical mechanisms that control changes in splice sites.

One major endeavor aims to identify splicing regulatory molecules and to determine their mechanisms of action. This uses the neural specific N1 exon of the c-src gene as a model for biochemistry.

A second major effort is directed at understanding how cell-signaling pathways impact the splicing reaction. This project focuses on the effect of cell excitation on the splicing of ion channel transcripts and the role of these splicing changes in neuronal plasticity.

Other interests within the lab include the development of oligonucleotide microarrays to assay splicing, examining the biological role of specific splicing factors in knockout mice, and understanding how the coupling of splicing to transcription affects splice site choice.
