Abstract

fetched live from OpenAlex

Ubiquitin Specific Protease 7 (USP7) catalyzes the deubiquitination of several substrate proteins including p53, Mdm2 and UbE2E1. Deubiquitination results in their rescue from 26S proteasome mediated degradation thus USP7 is critical in maintaining the cellular steady state levels of its substrates. USP7 is also known to interact with several viral proteins including herpes simplex virus Infected Cell Protein 0 (ICP0), Epstein Barr Nuclear Antigen 1 (EBNA1) and Kaposi's sarcoma-associated viral interferon regulatory factor 4 (vIRF4). USP7 possesses several domains including an N-terminal TRAF, a catalytic and five ubiquitin-like domains. The crystal structures of several complexes revealed that most substrate proteins interact with the N-terminal domain of USP7 which folds into an eight-stranded antiparallel beta sandwich. EBNA1 and MCM-BP also interact with USP7 through its N-terminal domain in an identical manner to its substrates p53, Mdm2 and UbE2E1 however these proteins are not deubiquitinated by USP7. Substrates that interact with USP7 through its N-terminal domain possess a P/AxxS binding motif. The identification, characterization and structure determination of novel USP7 substrates is ongoing.

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.
