Annexin A2 is SUMOylated on its N‐terminal domain: Regulation by insulin
Bibliographic record
Abstract
Insulin receptor (IR) endocytosis requires a remodelling of the actin cytoskeleton. We show here that ANXA2 is SUMOylated at the K10 located in a non-consensus SUMOylation motif in the N-terminal domain. The Y24F mutation decreased the SUMOylation signal, whereas insulin stimulation increased ANXA2 SUMOylation. A survey of protein SUMOylation in hepatic Golgi/endosome (G/E) fractions after insulin injections revealed the presence of a SUMOylation pattern and confirmed the SUMOylation of ANXA2. The construction of an IR/ANXA2/SUMO network (IRASGEN) in the G/E context reveals the presence of interacting nodes whereby SUMO1 connects ANXA2 to actin and microtubule-mediated changes in membrane topology. Heritable variants associated with type 2 diabetes represent 41% of the IRASGEN thus pointing out the physio-pathological importance of this subnetwork.

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.
