Description
VGLL4 (Vestigial Like Family Member 4) encodes a transcriptional cofactor that interacts with TEAD transcription factors to regulate Hippo signaling pathway target genes. It acts as a tumor suppressor by competing with YAP/TAZ for TEAD binding, thereby inhibiting cell proliferation and promoting differentiation. VGLL4 is involved in development, tissue homeostasis, and its dysregulation is implicated in multiple cancers.

Protein Summary
VGLL4 is a 299-amino-acid protein containing a Tondu (TDU) domain that mediates interaction with TEAD transcription factors. It functions as a transcriptional cofactor that can both activate and repress gene expression depending on context. By competing with YAP/TAZ for TEAD binding, VGLL4 acts as a critical negative regulator of the Hippo pathway, suppressing cell proliferation and tumorigenesis. The protein is predominantly nuclear but can also localize to the cytoplasm.
