Molecular Biology Program
The overarching mission of the Molecular Biology Program at SKI is to understand the mechanisms that promote the integrity and expression of genetic information. Defects in the network of pathways that are integrated to preserve genome integrity are highly correlated with malignancy. This network, known as the DNA damage response, comprises DNA repair functions and DNA damage signaling, as well as the downstream outputs of signaling that include apoptosis and transcriptional changes. The focus of our genomic integrity research is on understanding the mechanisms and mediators of the various processes that make up the DNA damage response.
Researchers in our program utilize a broad range of experimental approaches such as genetics in mice, yeast, and bacteria as well as biochemistry, structural biology, and molecular biology to illuminate fundamental mechanistic features of biological processes.
Our interests include, but are not limited to:
- regulation of the cell cycle
- mechanisms that underlie accurate transmission of chromosomes during cell division
- DNA damage signaling
- mutagenesis and genome rearrangement
- mechanisms and regulation of DNA replication
- functions and metabolism of RNA
- programmed gene rearrangement pathways
- regulation of RNA repair and translation
- chromatin assembly during DNA replication and transcription
