Cell biologist at NIH researching mechanisms of protein and organelle transport, and related diseases. Special interest in neurons and neurodevelopmental disorders. Science, nature, travel, and music enthusiast. Views are my own.
New study from our lab at NICHD, NIH! We identify TBC1D9 and TBC1D9B as novel ARL8 effectors that suppress exosome secretion by inactivating RAB11A and thus blocking exocyst-dependent fusion of multivesicular endosomes with the plasma membrane. www.pnas.org/doi/10.1073/...
By the way, @dshb-antibodies.bsky.social is a non-profit that sells quality antibodies to many proteins at exceptionally reasonable prices, without AI generated faux-validation images. Check them out. dshb.biology.uiowa.edu

Someone in the news departments of @nature.com or @science.org needs to take a look at this--its a huge scandal from the scientific supplier that has become a monopoly
Awesome achievement! Sabastian Sawe of Kenya becomes first person to run a sub-2-hour marathon to win in London apnews.com/article/mara...

Many thanks, @depaceraffa.bsky.social! I am deeply honored by this recognition and grateful to all who made it possible. 🙏
Congratulations to @juanbonifacino.bsky.social at the NIH on his election to the American Academy of Arts and Sciences — one of the nation's most prestigious honorary societies — in recognition of his distinguished contributions to cellular and developmental biology! 🎉 www.amacad.org/new-members-...
New work from Niccolo Mencacci @feinberg.northwestern.edu et al., with contribution from @depaceraffa.bsky.social in our lab at the NIH, identifies pathogenic variants in BORCS5, encoding a subunit of the BORC complex, as a cause of a severe neurodevelopmental disorder. www.jci.org/articles/vie...

Take a look at our Research Highlight: Adriana Golding et al. www.nature.com/articles/s41... We highlight the work by Ghoochani et al., who generated an atlas of brain lysosomal proteins and identified SLC45A1-associated disease as a lysosomal disorder: www.cell.com/cell/fulltex...

Fluorescence Friday - DNA-PAINT imaging of axon initial segment TRIM46 ('cyan') and bIV spectrin ('red') by the incomparable Allison Melton in my laboratory. Just spectacular!
Two postdoc positions in way lab go live tomorrow......please pass the message along.......more details to follow.
Structure of the adaptor protein 4 (AP-4) complex revealed! AP-4 exists in a dynamic equilibrium between closed and open conformations in solution. ARF1 does not shift this equilibrium but is required—together with cargo—for membrane recruitment. rdcu.be/e1ozM
Highly recommend! Great mentor and environment.
I’m recruiting new members to the Farrell Lab this summer. We will have space for 1 postdoc (since Abhinav is leaving to start his own lab at U Arizona!!) and 2 postbacs, since my current two will leave for PhD programs at the end of the summer. More details in thread:
Our wonderful technician Xiaolin (Lin) Zhu is retiring after 27 years of dedicated service in our lab. We will miss her greatly, but we are happy for her as she begins this well-deserved new chapter in her life.
This year I had the chance to see Edvard Munch’s The Sick Child painting in Oslo. It’s a powerful reminder of what our Institute, NICHD, NIH, works to prevent and cure.
My lab in the NIH Intramural Program (Bethesda, MD) will be recruiting postdoctoral fellows over the next year with flexible start dates. We work on nanoscale cellular imaging of the plasma membrane and related organelles. Please reach out if you’re interested. www.training.nih.gov/jobs/pdp-053...
Latest preprint from our lab reports that the distinct pH of anterograde (less acidic) and retrograde (more acidic) lysosomal vesicles in the axon depends on assembly of the V1 and V0 domains of the vacuolar H+ ATPase, mediated by the metazoan RAVE complex www.biorxiv.org/content/10.6...
Interesting findings linking RAB14 to the EARP complex and the lipid transfer proteins SHIP164 and UHRF1BP1 on endosomes!
It is a nice way to end the week: our improved RAB GTPase BioID map now online! www.nature.com/articles/s42... We hope it will be useful to the community, and we're happy to share any reagents!
Painted tonight, but it’s nowhere near done, so instead here’s a piece I did in 2024 called Frosty Twilight (16”x20” mixed media). I went through a whole birches phase and this was part of that series. Anyhoooo….who’s ready for Monday?! I’m not! Lol #art #painting #mixedmedia #sundayscaries
This paper was a tour de force and would not be possible without he help of so many collaborators like @juanbonifacino.bsky.social and many more. Thank you!!!
Excited to announce the YAK lab's first paper and the discovery of the FIRST human cellular PRF signal to give access to two overlapping open reading frames (science.org/doi/10.1126/...)! Before we dive in, the story actually begins in a Nature from 11 years ago
Excited to share our latest manuscript by @saikat2025.bsky.social and an international team, reporting variants in the EARP- and GARP-interacting protein EIPR1 associated with a neurodevelopmental disorder. Will send you the PDF if you can’t access the article: academic.oup.com/brain/articl...
EIPR1 variants cause a neurodevelopmental disorder with endolysosomal and dense core vesicle defects
Abstract. EIPR1 (EARP-interacting protein 1, formerly known as TSSC1) is a WD40-domain protein that interacts with the EARP (endosome-associated recycling
