Helpful paper unpacking some metrics and intuition behind higher success rate (10-fold?) of designing protein binders using DL and/or physics-based methods alone

The mechanism of this new motor is distinct from conventional ones.
Unlike motors such as Kinesin, it runs on GTP not ATP.
Also, the motor has no "power stroke" motion of one protein domain relative to another, but relies on a sudden change in the stiffness of the en…

Super cool observations! Not entry, not copy #, but lack of histone modifications affecting transgene expression

I want to especially thank my BB405,503 UG course professors @patankar_lab @Banerjeeiitb, who taught molecular biology in a way that probably changed the course of my academic interests ever since.
Also excited to get 'The Eighth Day of Creation' by Judson as my celebratory book

Looking to study chromatin interactomes with proximity labeling? Check out our new paper in @Nature, where we combine our split-intein expertise with uMap technology from the @MacMillan_Lab to map the microenvironment of chromatin state changes.

Delighted to share that I recently had the chance to talk about my work on development of highly energy-efficient “beyond CMOS” devices, based on magnetics, spintronics and magnetoelectrics, at @TEDxBoston 's Planetary Stewardship forum.
For writing #tootorial, I’ve used the trick where the first toot is Public but the rest are Unlisted. The top post will be the one that shows up in followers timelines, rather than all of them in reverse order.
I think the Unlisted ones can be boosted by others, but they aren’t searchable though, which is a downside.

@ypriverol had a conversation with a new data science student looking at a high throughput screen. They asked, how do you approach this as a statistician? I said, make plots, more plots, keep making plots. Raw data, summary stats, typical features/cases, exceptional features/cases. Student asked, can AI help in this process? Me: not really, this is where the human 👁️ and 🧠 are your best tools, to then provide quality data for models to learn meaningful patterns instead of artifacts and bias
For eg, in the last few days,
{I have been listening to talks on BCI, explaining to friends about an experience when I wanted to understand someone’s approach to a problem, thought about watching one of the Harry Potter movies, read about José’s blog embeddings}
..hence,Pensieve?
The key point being that the dissection is in a way that it is immediately obvious to understand your idea/thought/feeling and how you arrived at it at the moment, if you/anyone revisited it in future, and in a way that cannot be corrupted by any biases/assumptions
🚨New preprint posted🚨
Protein turnover is regulated by learning and disease processes. We developed a method (DELTA) to quantify the rate of protein turnover across the whole brain, with single synapse resolution.
https://www.biorxiv.org/content/10.1101/2022.11.12.516226v1
We used knock-in mice in which a protein of interest is fused with HaloTag, a self-labeling enzyme which can capture bright Janelia Fluor dyes. This is the basis of a pulse-chase experiment to estimate turnover rates.
