Electrophysiological characterization of a mitochondrial inner membrane chloride channel in rat brain
Bibliographic record
Abstract
Mitochondria are an essential component of cellular integrity and homeostasis, and their functions and pathological processes are highly dependent on mitochondrial ion channels. Anion channels of the inner mitochondrial membrane have been described by direct patch-clamp electrophysiological methods in mitoplasts prepared in cardiac, liver, and brown adipose tissue, but not in brain. Here, using acutely isolated rat brain mitoplasts, we describe the properties of a large conductance, voltage-gated, pH-sensitive, outwardly rectifying chloride channel with conductances of 98 pS and 129 pS at negative and positive membrane potentials, respectively. While the molecular identity of this chloride conductance is unknown, it is unlikely to be a CLIC channel due to differences in the observed electrophysiological properties.

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.
