Abstract: WW-binding protein 2 (WBP2) has been demonstrated in different studies to be a tyrosine kinase substrate, to activate ER?/PR transcription and to play a role in breast cancer. However, the role of WBP2 tyrosine phosphorylation in regulating ER function and breast cancer biology is unknown. Here, we established WBP2 as a tyrosine phosphorylation target of estrogen signaling via EGFR crosstalk. Using dominant negative, constitutively active mutants, RNAi and pharmacological studies, we demonstrated that phosphorylation of WBP2 at Tyr192 and Tyr231 could be regulated by c-Src and c-Yes kinases. We further showed that abrogating WBP2 phosphorylation impaired >60% of ER? reporter activity putatively by blocking nuclear entry of WBP2 and its interaction with ER?.
