Group members also study the functions of the MARCKS family of protein kinase C substrate proteins in the normal development of the brain and retina, and the role of a recently described transcription factor, Rfx4_v3, in brain development. Methods used in this research range from structural biology and enzyme kinetics to mouse and human genetics. The Polypeptide Hormone Action Group is interested in the mechanisms by which signals are transduced after the binding of polypeptide hormones and other agonists to their surface receptors on cells, later resulting in a wide variety of cellular responses.

Current projects:
Perry J. Blackshear, M.D., D.Phil., heads the Polypeptide Hormone Action Group within the Laboratory of Signal Transduction. He is also Director of Clinical Research and Acting Director of Intramural Research at NIEHS. He received his Doctor of Philosophy degree from Oxford University in 1974, and his M.D. from Harvard Medical School in 1977. He has published more than 200 peer-reviewed articles in leading biomedical journals, as well as several book chapters. He served as an Investigator with the Howard Hughes Medical Institute at Duke University, where he was also a Professor of Medicine and of Biochemistry, before joining NIEHS in 1997. |
