Investigation of the effect mutations of CaM have upon in vitro and ex vivo function
Bibliographic record
Abstract
Calmodulin (CaM) is a calcium-binding protein that has promiscuous regulatory interactions with over three hundred intracellular protein targets. The focus of this study was to characterize the functional role of phosphorylated CaM in vitro and calcium-deficient CaM (Apo-CaM) ex vivo. In the in vitro study, the effect of phosphorylated CaM on the binding and activation of CaM target proteins was analyzed using mammalian Nitric Oxide Synthase (NOS). NOS is an enzyme that catalyzes the conversion of L-arginine to L-citrulline and •NO. In addition, the activation of NOS by modified CaM proteins was also analyzed in the presence of a CaM binding peptide, PEP-19. \nProtein trafficking experiments were performed ex vivo to extend our understanding of Apo-CaM’s functional role in mammalian cells. The cell lines that were used in this investigation include mouse Embryonic Stem Cells (mESC), Human Umbilical Vein Endothelia Cells (HUVEC) and Human Neuronal Glioma Cells (HNGC). \nThe major finding of this projects are: phosphorylation of selective CaM residues can attenuated NOS activity, electrostatic interactions are important in the activation of iNOS by CaM, and the activation of iNOS by CaM occurs in a calcium-dependent manner

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
