Since GATA3 has been reported to interact with menin in lymphocytes [26], and menin is known to interact with one member of the FOXA family, FOXA2 [27], we performed immunoprecipitation (IP) and PLA analyses to determine whether menin could interact with GATA3 and FOXA1 in breast cancer cells. The gene discussed is GATA3; the disease is breast cancer.
