Residue burial encodes a protein's fold Protein structure is controlled by a high-dimensional energy landscape, which is a function of all of the atomic coordinates of the protein. Can this landscape be accurately described by a low-dimensional representation? We find that residue core identity, a binary N-dimensional encoding indicating whether each of the N amino acids in a protein is buried in the core or not, can predict the protein's backbone conformation more efficiently than all other representations that we tested. Core identity is 4 times more efficient than previous estimates of the bits per residue needed to encode a protein's native fold, 2 times more efficient than the Cα contact map, and 1.5 times more efficient than the machine-learned embeddings from FoldSeek's 3Di. Even when the folded structure is unavailable, predicting each residue's burial from sequence yields a more accurate estimate of fold quality than predicting pairwise contacts from the same sequence information. Thus, this work emphasizes that the problem of determining a protein's native fold can be re-framed as predicting each residue's core identity. ### Competing Interest Statement The authors have declared no competing interest. Chan Zuckerberg Initiative (United States), 2023-329572 NIH, T32GM145452

How much information does it take to fold a protein? Not much, if you use the right information! We find that residue burial, a binary label of core vs surface, encodes a protein's fold highly efficiently and even improves ESM2's structure representation. 1/8 www.biorxiv.org/content/10.6...

Foundational work in #zebrafish can be credited to "fruitful" discussions between #Drosophila researchers such as José Campos-Ortega & Christiane Nüsslein-Volhard. By the late 1980s, multidisciplinary approaches honed in flies were finally applied to a vertebrate. #ZebrafishFunFacts 🧪

So called microtubule organizing centers (MTOCs) are not "organizing centers". They don't control their position (network center), nor MT orientation, length and shape (network shape). The actual organizers are MTs, molecular motors and regulators of MT +ends. MTOCs nucleate MTs.
Let's rename MTOCs.

How can we organize current theoretical approaches for developmental biology - from information to dynamical systems & GRNs - into a common framework?
