Abstract

fetched live from OpenAlex

Human heat shock protein 27 (Hsp27) is an oligomeric and cell survival protein that has been associated with several cancers including prostrate and breast cancer. It's a known anti-apoptotic protein that functions as a molecular chaperone for several proteins. Hsp27 characteristically binds and stabilizes numerous partially unfolded proteins preventing their degradation, and has been shown to prevent actin polymerization in vitro. Several actin-binding residues involved in this interaction have been identified at the N-terminal loop and highly conserved alpha crystallin domains of Hsp27. Multiple assays have demonstrated that this hydrophobic actin-binding site is also involved in other protein binding. We therefore propose a common substrate-binding region on Hsp27 and present a model of Hsp27 binding to actin.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
