TRPV5 and breast cancer: Additionally, it interacts with the epithelial Ca2+ channel TRPV5 (Transient Receptor Potential Cation Channel Subfamily V Member 5) in HEK293 cells (16), plays a role in fibroblast growth factor (FGF) signaling in human breast cancer cells and rat myoblast cells (5, 17), and is implicated in intracellular vesicle transport in CHO (18).
