14-3-3<i>γ</i> affects eIF5 to regulate <i>β</i>-casein synthesis in bovine mammary epithelial cells
Bibliographic record
Abstract
The 14-3-3γ protein participates in many biological processes; however, its regulatory mechanism in milk protein synthesis is not well studied. We hypothesized that 14-3-3γ might affect eIF5 (an initiation factor) to regulate β-casein synthesis in dairy cows. In this study, a possible interaction between 14-3-3γ and eIF5 was investigated using bovine mammary epithelial cells (BMECs). The expression levels of 14-3-3γ and eIF5 in the mammary gland tissues from cows producing higher quality milk were higher than those from cows producing low-quality milk. Moreover, the expression of 14-3-3γ, eIF5, and β-casein were increased at both mRNA and protein levels in BMECs cultured in vitro with methionine (Met) supplementation. Coimmunoprecipitation, colocalization, and FRET analysis further showed the evidences that 14-3-3γ physically bound to eIF5 in BMECs. Gene function studies revealed that 14-3-3γ positively regulated eIF5 through alteration of eIF2α/p-eIF2α ratio. Collectively, our data suggest that 14-3-3γ regulates β-casein translation in BMECs through interaction with eIF5.

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.
