VGLL4 is acetylated at lysine 225, and this acetylation negatively regulates its binding to TEAD1. VGLL4 inhibits cardiomyocyte proliferation by inhibiting TEAD1-YAP interaction and by targeting TEAD1 for proteasomal degradation. An acetylation-refractory VGLL4 mutant (K225R) shows enhanced TEAD1 degradation and limits neonatal CM proliferation. |

CDK1 phosphorylates VGLL4 during mitosis at Ser-58, Ser-155, Thr-159, and Ser-280. The non-phosphorylatable mutant VGLL4-4A (S58A/S155A/T159A/S280A) shows higher binding affinity to TEAD1 than wild-type VGLL4 and suppresses tumorigenesis more potently, indicating that mitotic CDK1 phosphorylation inhibits VGLL4's tumor-suppressive activity. |

Loss of VGLL4 reduces PD-L1 expression in tumor cells. VGLL4 interacts with IRF2BP2 and promotes its protein stability by inhibiting proteasome-mediated degradation of IRF2BP2. Loss of IRF2BP2 leads to persistent binding of IRF2 (a transcriptional repressor) to the PD-L1 promoter, thereby reducing PD-L1. Additionally, YAP inhibits IFNγ-inducible PD-L1 expression partly by suppressing VGLL4 and IRF1 via miR-130a. |

Biochemical characterization shows that full-length VGLL4 and Drosophila Tgi are intrinsically disordered proteins. VGLL4 has two TEAD4-binding sites with one high-affinity site (100-fold tighter than the low-affinity site). In solution, VGLL4 predominantly forms dimeric complexes with TEAD4 via the high-affinity site; at high concentrations or when TEAD4 is immobilized/bound to DNA, one VGLL4 molecule can bridge two TEAD molecules, potentially enhancing repression at DNA-bound TEADs. |
