David G. Drubin is an American biologist, academic, and researcher. He is a Distinguished Professor of Cell and Developmental Biology at the University of California, Berkeley where he holds the Ernette Comby Chair in Microbiology.[1]

Drubin has published over 220 papers.[2] His research spans the areas of cell biology, genetics, and biochemistry. The approaches employed for these studies include real-time imaging of live cells, genome editing, mathematical modeling, genetics, and biochemistry. His lab studies human stem cells, stem-cell derived organoids, Zebrafish, and budding yeast to elucidate the molecular mechanisms that underlie highly dynamic subcellular events.[3]

Drubin is a Fellow of American Society for Cell Biology,[4] and a Senior Fellow at the Allen Institute for Cell Science.[5] He served as Editor-in-Chief for Molecular Biology of the Cell for 10 years,[6] advocating for civil and constructive peer review.[7] At the 2012 ASCB annual meeting in San Francisco he organized a meeting of journal editors to discuss the harmful effects of the Journal Impact Factor. This meeting produced the San Francisco Declaration on Research Assessment and earned the leaders of the effort SPARC Innovator Award recognition.[8]

He was elected a member of the National Academy of Sciences in 2022.[9]

Education

Drubin studied at the University of California, Berkeley, and the University of California, San Francisco, earning, respectively, his Bachelor's and Doctoral degrees in biochemistry in 1980 and Biochemistry and Biophysics in 1985. From 1985 until 1988, he held a Helen Hay Whitney Postdoctoral Fellowship at Massachusetts Institute of Technology (MIT).[1]

Career

Following his Postdoctoral fellowship, Drubin was appointed as an Assistant Professor of Molecular and Cell Biology at the University of California, Berkeley in 1988. He was promoted to Associate Professor in 1994, and became Professor of Molecular and Cell Biology in 1998.[1]

Research

Drubin's research utilizes live-cell imaging, genetics, modeling and biochemistry to address fundamental questions concerning the cytoskeleton and membrane trafficking events in budding yeast and genome-edited human stem cells.[10]

Molecular and cell biology

While isolating the gene encoding microtubule-associated tau protein, a major player in Alzheimer's disease, Drubin developed cell culture models to study its biological function.[11] He distilled general principles for cell polarity development while defining it as the ultimate reflection of complex mechanisms that establish and maintain functionally specialized domains in the plasma membrane and cytoplasm.[12] In a paper published in 2001, he guided establishment of a protein interaction map for cell polarity development, and determined a network of interactions that provide an integrated response of signaling proteins, the cytoskeleton, and organelles to the spatial cues that direct polarity development.[13]

Membrane trafficking and the cytoskeleton

Drubin studied mutants of over 60 proteins, identifying a pathway in budding yeast in which proteins are recruited to endocytic sites,[14] and also identified several protein modules that provide distinct functions in this pathway. He extended these studies to mammalian cells,[15] and determined the roles of these proteins in endocytosis and cell polarity development.[16] In the early 2000s, he outlined examples of functional cooperation between the microtubule and actin cytoskeletons, and highlighted two broad categories in this context: coordinated MT- and actin-based transport to move vesicles, organelles, and cell fate determinants; and targeting and capture of MT ends at cortical actin sites.[17]

Actin assembly

In his studies on actin assembly, Drubin demonstrated that although budding yeast are nonmotile, their actin filaments turn over at high rates and he defined the roles for actin in establishment and maintenance of cell polarity while using and popularizing the actin inhibitor latrunculin-A.[18] He established that cofilin is largely responsible for actin filament high turnover rate.[19] He conducted structure-function analysis of actin, described mutating residues involved in nucleotide hydrolysis, and also demonstrated the effects of these mutations on actin assembly in vitro and in vivo.[20] His studies further addressed the role of nucleotide in Arp2/3 function, and highlighted several novel activators of the Arp2/3 complex,[21] which regulates actin nucleation. He has also developed a complex actin assembly system on the surface of microbeads incubated in yeast cell extracts, and has extended this work toward reconstituting complex actin-based trafficking events on supported lipid bilayers.[22]
