Nitrosative modifications of protein and lipid signaling molecules by reactive nitrogen species
Bibliographic record
Abstract
This review is the last of four review articles addressing covalent modifications of proteins and lipids. Two of the reviews in this series were previously published (15, 28) and dealt with modifications of signaling proteins by GlcNAcylation and serine phosphorylation. In the current issue of the Journal, we complete this series with two reviews, one by Riahi et al. (102a) on the signaling and cellular functions of 4-hydroxyalkenals, key products of lipid peroxidation processes, and our present review on the effects of nitrosative modifications of protein and lipid signaling molecules by reactive nitrogen species. The aim of this Perspectives review is to highlight the significant role that reactive nitrogen species may play in the regulation of cellular metabolism through this important class of posttranslational modification. The potential role of nitrosative modifications in the regulation of insulin signal transduction, mitochondrial energy metabolism, mRNA transcription, stress signaling, and endoplasmic reticulum function will each be discussed. Since nitrosative modifications are not restricted to proteins, the current understanding of a recently described genus of "nitro-fatty acids" will also be addressed.

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.
