Characterization of two alternative splice variants associated with the <i>Arabidopsis</i> rhomboid protein gene At1g25290
Bibliographic record
Abstract
Rhomboid proteases are involved in various cellular activities, from development to cancer, and cellular processes and substrates associated with rhomboid proteases or rhomboid-like proteins have been identified for a range of organisms. Plant rhomboid proteases or rhomboid-like proteins are the least understood of the group. Moreover, the general phenomenon of alternative splicing and rhomboid protein genes has yet to be studied robustly. This study thus focused on the alternative splicing events associated with the Arabidopsis rhomboid protein gene At1g25290. The patterns obtained through RT-PCR and DNA sequencing provided evidence of alternative splicing in the At1g25290 transcript population, especially in the region spanning exons 5 and 6. The levels of the two splice variants involving exons 5 and 6 appear to be sufficiently abundant to possess functional significance and appear to adjust relative to each other in different contexts. Adjustments were observed in tissues of different developmental stages, in an Arabidopsis plant bearing a mutation in another rhomboid protein, and in response to transgenic manipulations affecting the levels of Tic40, a plastid translocon component. The resulting change to the protein sequence may, in turn, affect how At1g25290 proteins interact with their substrates. Collectively, the evidence suggests that alternative splicing of At1g25290 bears functional significance in Arabidopsis.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
