Abstract

fetched live from OpenAlex

Abstract von Hippel–Lindau protein (pVHL) is the tumor suppressor responsible for ubiquitylating the hypoxia‐inducible factor (HIF) family of transcription factors for degradation under normoxic conditions. There are two major pVHL isoforms with the shorter isoform (pVHL19) lacking the acidic domain present in the N‐terminus of the longer isoform (pVHL30). Although both isoforms can degrade HIF and suppress tumor formation in experimental systems, previous research suggests that pVHL30 can undergo posttranslational modifications (PTM) and interact with unique proteins. Indeed, pVHL30 has long been observed to migrate as two species on a reducing polyacrylamide gel, indicating the presence of an uncharacterized PTM on the slower‐migrating pVHL30 without an identifiable biological consequence. Thus, there has been considerable effort to elucidate the exclusive biological activity of pVHL30, if any, by first defining the unique features of the slower‐migrating species. We show here that the migration of pVHL30, but not pVHL19, is retarded by 4‐(2‐aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF), an irreversible serine protease inhibitor commonly found in protease inhibitor cocktails.

Not 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.
