Highlights
Vgll1-TEAD complex is structurally similar to the YAP-TEAD complex
Structural similarity is striking as Vgll1 and YAP have a different primary sequence
These complexes upregulate proliferation-promoting genes
They also induce anchorage-independent cell proliferation
Summary
The structure of the complex between the transcription cofactor Vgll1 and the transcription factor TEAD4,, the mammalian equivalent of the Drosophila Vestigial and Scalloped,, respectively, is determined in this study. Remarkably,, Vgll1 interacts with TEAD in a manner similar to the transcription coactivators,, as well as oncogenes YAP and TAZ, despite having a varied primary sequence. Vgll1-TEAD complex upregulates the expression of IGFBP-5,, a proliferation-promoting gene,, and facilitates anchorage-independent cell proliferation. The YAP/TAZ-TEAD complex also upregulates several other proliferation-promoting genes and also promotes anchorage-independent cell proliferation. Given its structural and functional similarity to YAP/TAZ, Vgll1 has the potential to promote cancer progression.
