GENES AND PROTEINS THAT CONTROL THE SECRETORY PATHWAY Nobel Lecture, 7 December 2013 by RANDY SCHEKMAN Department of Molecular and Cell Biology, Howard Hughes Medical Institute, University of California, Berkeley, USA. Introduction George Palade shared the 1974 Nobel Prize with Albert Claude and Christian de Duve for their pioneering work in the characterization of organelles interrelated by the process of secretion in mammalian cells and tissues. These three scholars established the modern field of cell biology and the tools of cell fractionation and thin section transmission electron microscopy. It was Palade’s genius in particular that revealed the organization of the secretory pathway. He discovered the ribosome and showed that it was poised on the surface of the endoplasmic reticulum (ER) where it engaged in the vectorial translocation of newly synthesized secretory polypeptides (1). And in a most elegant and technically challenging investigation, his group employed radioactive amino acids in a pulse-chase regimen to show by autoradiograpic exposure of thin sections on a photographic emulsion that secretory proteins progress in sequence from the ER through the Golgi apparatus into secretory granules, which then discharge their cargo by membrane fusion at the cell surface (1). He documented the role of vesicles as carriers of cargo between compartments and he formulated the hypothesis that membranes template their own production rather than form by a process of de novo biogenesis (1). As a university student I was ignorant of the important developments in cell biology; however, I learned of Palade’s work during my first year of graduate school in the Stanford biochemistry department. -

The Roles of TAL Effectors in Nature in Relation to Their Unique Properties As DNA-Targeting Tools
The Roles of TAL Effectors in Nature in Relation to their Unique Properties as DNA-Targeting Tools Adam Bogdanove Cornell University Ithaca, New York [email protected] I will present perspectives on the unique properties of TAL effectors as DNA-targeting tools, and what we can gain from understanding how they work in nature and in plant disease. I’ll begin by comparing and contrasting the CRISPR/Cas9 and TAL-effector nuclease (TALEN) systems to highlight some of the unique features of the latter (Figure 1). TAL-effector nucleases work as dimer proteins. Each individual monomer of the TAL-ef- fector domain is about 102 kDa. Targets are encoded by repeats in each protein. In contrast with CRISPRs, typically you need one dimer per target, so it’s not readily multiplexed, certainly not as readily as the CRISPR/Cas9. The targeting specificity is typically 15 to 20 bases times 2. Therefore, on the surface, in these base configurations, TAL effectors inherently have great specificity, but, as we heard from Dan Voytas1 and Ann Ran2, a number of tricks have been applied within the CRISPR/Cas9 architecture to improve their specificity. So, they are complementary, effective systems. 1Pages 29–37. 2Pages 69–81. 3 Figure 1. Comparison of DNA-targeting systems. (Images adopted from van der Oost, 2013) TALEN Utility I was interested to see what would happen in the genome-editing field as CRISPRs gained momentum with possibly less emphasis on TAL effectors. However, a proliferation of TALEN kits have been deposited with Addgene3—which Dan Voytas4 and I are familiar with because we deposited there—and over 1,400 requests have been filled for our kit. -

University of California Berkeley Regional Oral History Office University of California The Bancroft Library Berkeley, California Program in the History of the Biosciences and Biotechnology Arthur Kornberg, M.D. BIOCHEMISTRY AT STANFORD, BIOTECHNOLOGY AT DNAX With an Introduction by Joshua Lederberg Interviews Conducted by Sally Smith Hughes, Ph.D. in 1997 Copyright 1998 by The Regents of the University of California Since 1954 the Regional Oral History Office has been interviewing leading participants in or well-placed witnesses to major events in the development of Northern California, the West, and the Nation. Oral history is a method of collecting historical information through tape-recorded interviews between a narrator with firsthand knowledge of historically significant events and a well- informed interviewer, with the goal of preserving substantive additions to the historical record. The tape recording is transcribed, lightly edited for continuity and clarity, and reviewed by the interviewee. The corrected manuscript is indexed, bound with photographs and illustrative materials, and placed in The Bancroft Library at the University of California, Berkeley, and in other research collections for scholarly use. Because it is primary material, oral history is not intended to present the final, verified, or complete narrative of events. It is a spoken account, offered by the interviewee in response to questioning, and as such it is reflective, partisan, deeply involved, and irreplaceable. ************************************ All uses of this manuscript are covered by a legal agreement between The Regents of the University of California and Arthur Kornberg, M.D., dated June 18, 1997.

Running with (CRISPR) Scissors: Tool Adoption and Team Assembly
Running with (CRISPR) Scissors: Tool Adoption and Team Assembly Samantha Zyontz* MIT Sloan School of Management May 2019 Abstract Research tools are essential inputs to technological progress. Yet many new tools require specialized complementary know-how to be applied effectively. Teams in any research domain face the tradeoff of either acquiring this know-how themselves or working with external tool specialists, individuals with tool know-how independent of a domain. These specialists are scarce early on and can choose domain teams to create many applications for the tool or to focus on complicated problems. Ex ante it is unclear where the match between domain teams and external tool specialists dominates. The introduction of the DNA-editing tool CRISPR enables identification of external tool specialists on research teams by exploiting natural difficulties of applying CRISPR across disease domains. Teams have a higher share of external tool specialists in difficult diseases, especially for subsequent innovations. This suggests that external tool specialists and domain teams match more often to solve complex but influential problems. As more tools like Artificial Intelligence emerge, research teams will have to also weigh the importance of their possible solutions when considering how best to attract and collaborate with external tool specialists. * Ph.D. Candidate, MIT Sloan School of Management, Technological Innovation, Entrepreneurship, and Strategic Management. I am indebted to Scott Stern, Pierre Azoulay, Jeff Furman, Florenta Teodoridis, Michael Bikard, Danielle Li, and Tim Simcoe for their guidance and suggestions that immensely improved this paper. Appreciation also belongs to Joanne Kamens and her staff at Addgene, Aditya Kunjapur, Wes Greenblatt, and other CRISPR scientists for helping me to understand the science and institutions in this setting. -

A Review of J. Craig Venter's a Life Decoded
A peer-reviewed electronic journal published by the Institute for Ethics and Emerging Technologies ISSN 1541-0099 17(1) – March 2008 A review of J. Craig Venter’s A Life Decoded Randy Mayes, Duke University Journal of Evolution and Technology - Vol. 17 Issue 1 – March 2008 - pgs 71-72 http://jetpress.org/v17/mayes.htm In the early 1980s, a number of researchers suggested sequencing and mapping the human genome to help the science community better understand diseases and evolution. Following the announcement that the human genome had been sequenced, scientists wrote in peer-reviewed journals that we are not as hardwired as was once believed, and that the sequencing of the genome was just the beginning. Today, researchers have a new set of goals. In popular journalism, however, the science was lost in the shuffle. The media focused more on the dynamics of the conflicting philosophies of the private and public projects. This emphasis is also clear in the titles of several books chronicling the Human Genome Project, all appearing prior to the recent release of Craig Venter’s autobiography, A Life Decoded: My Genome: My Life (2007). Readers will find that Robert Cook-Deegan’s The Gene Wars (1995) and The Common Thread by Sir John Sulston and Georgina Ferry (2002), both written by insiders, are biased towards the philosophy of the public project, a commons approach. Sulston is a socialist who grows runner beans and drives a second hand car. By contrast, Venter travels in Lear jets and conducts business from his yacht. Three other books are more objective.
