We gathered for a picnic in beautiful North Berkeley to celebrate Matt’s time in the lab. We wish Matt the best in his new adventure and look forward to hearing about his lab’s accomplishments!
Cheers to Matt!
Matt catches up with his graduate school advisor, Tom Pollard, who happens to be one of our newest lab members.
Dr. Drubin’s video talk, Actin Dynamics and Endocytosis in Yeast and Mammalian Cells, is now available on iBiology.org: Link to Parts 1-4

The Drubin/Barnes lab would like to send our fondest farewells to Daphne, Itziar and Emily who are moving on to exciting new positions!
Daphne Dambournet is now working as a Cell line engineer at Memphis Meats working to grow sustainable cultured meat.
Itziar Ibarlucea has taken a position as a post-doctoral associate in the laboratory of Jeffrey Ravetch at The Rockefeller University.
Emily Stoops is now working as a Scientist at Calico where she is working to combat aging.
Congrats to Bob on passing his qualifying exam!

For Journal Club on August 6, Nate Krefman presented the following paper:
Centromere-like regions in the budding yeast genome. Lefrançois P, Auerbach RK, Yellman CM, Roeder GS, Snyder M. PLoS Genet. 2013;9(1):e1003209. PMID: 23349633.
CLRs confer centromere function on plasmids and chromosomes.
For Journal Club on August 6, Eric Lewellyn presented the following paper:
Actin filament severing by cofilin dismantles actin patches and produces mother filaments for new patches. Chen Q, Pollard TD. Curr Biol. 2013 Jul 8;23(13):1154-62. PMID: 23727096.
“Sever, diffuse and trigger” model for actin filament turnover in actin patches. The 7 steps (numbers next to the arrows) are (1) clathrin coated pits bind adaptor proteins End4p and Pan1p, (2) short, diffusing actin filaments bind to End4p and Pan1p associated with coated pits, and (3) Arp2/3 complex interacts with these mother filaments and nucleation promoting factors to (4) initiate branching nucleation of actin filaments that promote elongation of the endocytic tubule. (5) After abscission of the vesicle, (6) cofilin severs actin filaments to generate a pool of short, diffusing actin filaments, some of which return to the cycle at step 2.
