Abstract
Protein-RNA complexation is essential in cell biological functions. Transfer RNAs are bound to aminoacyl-tRNA synthetases for the translation of the genetic code during protein synthesis, while ribonucleoproteins bind RNA in posttranscriptional regulation of gene expression. A recent report showed the interacton of human serum albumin (HSA) with DNA duplex, in which two binding sites with strong and weak association constants were detected. We now examine the interaction of tRNA with human serum albumin (HSA) in aqueous solution at physiological conditions, using a constant RNA concentration of 12.5 mM (phosphate) and various HSA contents of 0.04 to 0.6 mM. Affinity capillary electrophoresis and FTIR spectroscopic methods were used to determine the protein binding mode, the association constant, sequence preference, and the biopolymer secondary structural changes in the HSA-RNA complexes. Spectroscopic evidence showed two types of HSA-RNA complexes with an overall binding constant of K = 1.45 x 10(4) M(-1). The major binding sites were located on the G-C bases and the backbone PO2 group. The protein-RNA interaction stabilizes the HSA secondary structure, and no major alterations of A-RNA structure or protein conformation occurred.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
