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). Here, TRPV5 is linked to breast carcinoma.
