A hyperglycosylated form of Kv <sub>1.2</sub> upregulated in LGI1 knockout mice
Bibliographic record
Abstract
Abstract Kv 1 voltage-gated potassium channels determine key functional neuronal properties. Their activity is modulated by subunit composition and post-translational modifications such as phosphorylation and glycosylation. Using an antibody directed against a phosphotyrosine (Y 458 ) located in the C-terminal tail of Kv 1.2 , we identified yet unreported high molecular weight forms of Kv 1.2 among them, a phosphorylated and heavily glycosylated 100 kDa form. Owing to the significant downregulation of Kv 1.2 in LGI1-dependent autosomal dominant lateral temporal lobe epilepsy, we investigated, in total brain and the hippocampal formation of both WT and Lgi1 -/- mice, the distribution of phosphoY 458 Kv 1.2 and we compared their respective proteomic interactomes with those of Kv 1.2 . In addition to major differences between the interactomes of pY 458 Kv 1.2 and Kv 1.2 in WT and Lgi1 -/- , we found a major reshaping of pY 458 Kv 1.2 molecular neighbourhood between WT and Lgi1 -/- as well as a significant upregulation of the glycosylated form in Lgi1 -/- .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
