G4600x Signal Transduction Fall 2007
Tuesdays 4:10 - 6:00 P.M. 800 Fairchild
Professors Ron Prywes (first half) and Daniel Kalderon (second half).
Prerequisites: Enrollment in the graduate program in Biological Sciences or permission of the instructor. Generally students with a solid background in biology (four or more courses) are accepted.
Text: The Biochemistry of Signal Transduction and Regulation, Third edition by Gerhard Krauss. This book has been ordered in the bookstore.
Students are required to read all research papers for discussion. They will also present specific papers to the class. There will be a midterm exam on October 16. In the second half of the course there will be problem set homework and a final paper is due on the last day of class. The final paper will consist of a research proposal with specific aims, background and research design sections. It should be 10-15 double-spaced pages. The topic must be approved by an instructor.

7. October 16 EXAM
The second half of the course will devote two sessions to each of three topics, as below. The accent in these classes is on the use of genetics and model systems to find out how signaling systems work to serve specific biological needs. Most of the work and learning is done outside the classroom by careful and critical reading of prescribed reviews and research papers. The precise papers to be covered will be posted later during the semester.
For 2003 the topics were:
8. & 9. Yeast pheromone and other MAP kinase pathways
10. & 11. TGF-beta family pathways
12. & 13. Wnt signaling pathways
