TENM4 is an essential transduction component for touch
Bibliographic record
Abstract
SUMMARY Gentle touch is conveyed to the brain by fast-conducting sensory fibers. Mechanosensitive ion channels at the terminals of these neurons are thought to be gated by extracellular tethers that transmit force from the surrounding matrix to the channel complex, but the molecular identity of such tethers has remained unknown. Here, we identify Teneurin-4 (TENM4) as an essential extracellular linker protein for mechanotransduction in mechanoreceptors. Sensory neuron–specific deletion of Tenm4 in mice caused profound touch insensitivity, while acute and reversible proteolytic disassembly of TENM4 at sensory endings confirmed its direct role in force transduction. Ultrastructural analyses revealed TENM4 localization to filamentous structures at the neurite–laminin interface, defining it as a structural component of the mechanosensory tether. These findings identify TENM4 as a core element of fast somatic sensation and provide molecular insight into how extracellular forces are coupled to ion channel activation.

How this classification was reachedexpand
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.
