Abstract
Chemokines are recognized as functionally important in many pathological disorders, which has led to increased interest in mechanisms related to the regulation of chemokine receptor (CKR) expression. Known mechanisms for regulating CKR activity are changes in gene expression or posttranslational modifications. However, little is known about CKR with respect to a third regulatory mechanism, which is observed among other seven-transmembrane receptor subfamilies, the concept of differential splicing or processing of heteronuclear RNA. We now report on the discovery of a variant human CKR, CXCR3, resulting from alternative splicing via exon skipping. The observed RNA processing entails a drastically altered C-terminal protein sequence with a predicted four- or five-transmembrane domain structure, differing from all known functional CKR. However, our data indicate that that this splice variant, which we termed CXCR3-alt, despite its severe structural changes still localizes to the cell surface and mediates functional activity of CXCL11.

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 it
