Abstract

fetched live from OpenAlex

Abstract Endoplasmic reticulum (ER) luminal Ca 2+ is vital for the function of the ER and regulates many cellular processes. Calreticulin is a highly conserved, ER‐resident Ca 2+ binding protein and lectin‐like chaperone. Over four decades of studying calreticulin demonstrate that this protein plays a crucial role in maintaining Ca 2+ supply under different physiological conditions, in managing access to Ca 2+ and how Ca 2+ is used depending on the environmental events and in making sure that Ca 2+ is not misused. Calreticulin plays a role of ER luminal Ca 2+ sensor to manage Ca 2+ ‐dependent ER luminal events including maintaining interaction with its partners, Ca 2+ handling molecules, substrates and stress sensors. The protein is strategically positioned in the lumen of the ER from where the protein manages access to and distribution of Ca 2+ for many cellular Ca 2+ ‐signalling events. The importance of calreticulin Ca 2+ pool extends beyond the ER and includes influence of cellular processes involved in many aspects of cellular pathophysiology. Abnormal handling of the ER Ca 2+ contributes to many pathologies from heart failure to neurodegeneration and metabolic diseases.

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.
