Kinkley lab / Chromatin Structure and Function Group
The higher order organization of DNA and chromatin in the nucleus impacts all nuclear processes including transcription, replication, DNA repair and cell division. Yet compaction past the 10nm fiber remains poorly understood. Our lab is interested in elucidating the mechanisms of higher chromatin order, the players involved and how dysregulation of these processes lead to disease or malignant phenotypes.

PHF13 Project: PHF13 is an H3K4me3 epigenetic reader involved in higher chromatin order, transcriptional regulation, DNA damage response, cell division and differentiation. We are working towards understanding the molecular interactions of PHF13 to elucidate how it modulates so many fundamental cellular processes and its impact on genome stability.
PHF13 and Higher Chromatin Order: PHF13 has been shown to impact mitotic chromatin compaction and structure, indicating a role in the highest levels of chromatin organization. Similarly, it has been shown to interact with several heterochromatin promoting proteins such as HP1 and Polycomb (PRC2), indicating a role as well in heterochromatin formation or maintenance. We strive to better understand the importance and function of PHF13 in these processes.
