EYA2 is an intrinsically cytosolic protein that is translocated to the nucleus by SIX family homeodomain proteins; activated Gαz and Gαi2 interact with the C-terminal Eya consensus domain of EYA2, prevent its nuclear translocation, and inhibit SIX/EYA2-mediated transcription from MEF3/TATA promoter elements. |

PAX3 is necessary and sufficient to induce expression of SIX1 and its cofactor EYA2 prior to MyoD and myogenin induction during myogenesis; dominant-negative PAX3 abolishes SIX1 and EYA2 expression, placing PAX3 upstream of EYA2 in the myogenic transcriptional cascade. |

Gαi1, Gαi2, and Gαi3 (but not Gαo) interact with EYA2 in an activation-dependent manner; coexpression of activated Gαi family members recruits EYA2 to the plasma membrane, prevents nuclear translocation, abrogates EYA2/SIX4-mediated transcription, and EYA2 reciprocally relieves Gαi2-mediated inhibition of adenylyl cyclase. |

EYA1 and EYA2 act genetically upstream of PAX3 in hypaxial dermomyotome formation; SIX proteins recruit EYA proteins to MEF3 DNA sites to drive transcription during somitogenesis; compound Eya1/Eya2 double-knockout embryos lose PAX3 expression in ventrolateral dermomyotomes and lack hypaxial myogenic progenitors, phenocopying Six1/Six4 double knockouts. |

Crystal structure of the EYA domain (ED) of human EYA2 at 2.4-Å resolution reveals it belongs to the haloacid dehalogenase (HAD) family with an elongated helix-bundle motif; catalytic and SIX-interacting sites are on opposite faces, and the DACH-binding site lies between them, suggesting DACH acts as a transcriptional switch linking phosphatase activity to SIX binding; two reaction intermediates (acyl-phosphate and hydrolysis transition state) were captured. |
