CRISPR screens in iPSC-derived neurons reveal principles of tau proteostasis CRISPR screens in iPSC-derived neurons reveal that the E3 ubiquitin ligase CRL5SOCS4 ubiquitinates tau, that CUL5 expression is correlated with resilience in human Alzheimer’s disease, and that electr...

After a long review process, I'm excited that our paper is finally in print: www.cell.com/cell/fulltex...

TL;DR: We use CRISPR screens in iPSC-derived neurons to find a new tau E3 ligase and a relationship between oxidative stress, the proteasome, and tau proteolytic fragments.

Zara Weinberg passed away earlier this week. She joined my lab earlier this year when her postdoc lab formally closed.
She was a brilliant scientist, supportive mentor, dear friend, avid music fan, rabid believer in public transit, open science champion, and above all just an amazing human.

Finally out!
I’m thrilled to share our new paper (Wolin et al., Cell 2025).

This paper describes SPIDR, a high-throughput method for mapping RBP binding sites.

By combining #SPIDR with #cryoEM, we identified the exact binding site of LARP1 within the #mRNA channel of the 40S ribosomal subunit.

Thanks Brooke! At UCLA students first need to be admitted into one of our graduate programs, so I can’t directly recruit grad students.

Hi Brooke, can I be added to your starter pack? Just opened a lab on mechanisms of stress response signaling (Lawrence-lab.org)

Hi Moe, can I be added to your starter pack? Just opened a lab on mechanisms of stress response signaling and metabolic regulation (Lawrence-lab.org)

Hey that protein looks familiar! 🦋

Exclusive: Famed protein structure competition nears end as NIH grant money runs out Agency silent on funding renewal for contest that inspired creation of AIs that predicted how proteins would fold

Speak up to prevent a major loss for the field. CASP, which helped shaping structural biology including AlphaFold is on the verge of shutting down. NIH funding has lapsed, UC Davis support ends and the core team is being let go. Painfully shortsighted.

I'm excited to share our latest story from the
@lydiafinley.bsky.social lab, where we show that it's not just whether cells take up nutrients that matters, but how and where those metabolites are used. Out now in @naturemetabolism.bsky.social: rdcu.be/ejFTs 1/

Woohoo congrats John! 🎉

Happy that my first paper from my Postdoc is out where we perform Phospho-seq, a single-cell ATAC-sequencing with intracellular protein quantification in human brain organoids: www.nature.com/articles/s41...

So excited to co-chair this session with @herrflow.bsky.social tomorrow! Come hear cool talks ranging from computational to experimental approaches to understand protein dynamics and allostery!

Attending #BPS2025? Want to know more about tangible steps you can take to challenge the attacks on science in the U.S.? Please attend an Emergency Town Hall Meeting on Tuesday at 1:30! @biophysicalsoc.bsky.social @blackinbiophys.bsky.social Please spread the word!

Great news, great opportunity for students and postdocs!!

Hi Sarah, can you add me? Thanks for making this list!

Thank you Krishna!

I’d love to be added!

Thanks for making this! Can you add me?

Thank you! 😊

So cool! I'd love to be included!

First post on bluesky gotta be the structure of mTORC1 on membrane! A great collaboration and interesting frontier for SPA cryoEM!

Stunning! Congrats Zhicheng!

@kampmann.bsky.social

We add new data:

1. A new CRL5 complex that targets tau for degradation
2. CUL5 as a marker of vulnerability in Alzheimer's Disease
3. Oxidative stress-derived tau fragments change in vitro tau aggregation

Thanks @tlnagy.bsky.social ! I'm excited to join the UCLA community 😊
