MOB1 regulates thymocyte egress and T‐cell survival in mice in a YAP1‐independent manner
Bibliographic record
Abstract
Abstract Mammalian STE20‐like protein kinase 1/2 (MST1/2) and nuclear Dbf2‐related kinase 1/2 (NDR1/2) are core components of Hippo signaling that are also known to be important regulators of lymphocyte trafficking. However, little is understood about the roles of other Hippo pathway molecules in these cells. Here, we present the first analysis of the function of Mps one binder kinase activator‐1 (MOB1) in T lymphocytes in vivo . T‐cell‐specific double knockout (DKO) of MOB1A/B in mice [t Mob1 DKO mice] reduces the number of naïve T cells in both the circulation and secondary lymphoid organs, but leads to an accumulation of CD4 + CD8 − and CD4 − CD8 + single‐positive (SP) cells in the thymus. In vitro , naïve MOB1A/B‐deficient T cells show increased apoptosis and display impaired trafficking capacity in response to the chemokine CCL19. These defects are linked to suppression of the activation of MST and NDR kinases, but are independent of the downstream transcriptional co‐activator Yes‐associated protein 1 (YAP1). Thus, MOB1 proteins play an important role in thymic egress and T‐cell survival that is mediated by a pathway other than conventional Hippo‐YAP1 signaling.

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.
