RIC8A and ovarian carcinoma: In addition to identifying Ric-8A as one of the majorGα13-interacting proteins, we also establish the endogenousinteraction between Gα13 and Ric-8A in ovarian cancer cells.Furthermore, our TAP-couple mass spectrometric analysis indicates that Ric-8A isphosphorylated at Ser-436, Thr-441, Thr-443 and Tyr-435.
