Abstract

fetched live from OpenAlex

Siva1 protein interacts with tumor protein p53 and with the member of the tumor necrosis factor receptor superfamily, stathmin, among others. These proteins are related to several pathways involved in cancer and are therefore strong candidate targets for drug design. This study aimed to characterize the biophysical properties of Siva 1 C- terminal domain to contribute to the discovery of new target directed drugs. Siva1 protein interacts with tumor protein p53 and with the member of the tumor necrosis factor receptor superfamily, stathmin, among others. These proteins are related to several pathways involved in cancer and are therefore strong candidate targets for drug design. This study aimed to characterize the biophysical properties of Siva 1 C- terminal domain to contribute to the discovery of new target directed drugs. The C-terminus Siva1 domain (residues 84-175) was fused to glutathione Stransferase (GST) and expressed in an E coli system and the recombinant GST-Siva C-terminus was purified by GSTTagged Protein affinity and gel filtration chromatography. We tested the biological activity of the purified Siva Cterminus domain in a Jurkat extract cell line and found that the protein interacted with natural binders. Biophysical and biochemical assays have demonstrated monodispersion of the protein in solution with a predominant unfolded and elongated shape. However, at high concentrations, the protein showed a tendency to form soluble aggregates. These results are expected to lead to further progress in the understanding of Siva1 properties and target-directed drug design.

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.
