GIPC1, also known as GAIP interacting protein, C terminus 1, is a multifunctional scaffold protein. It plays diverse roles in multiple biological processes. It binds to various proteins and is involved in signaling pathways such as PDGFR/PI3K/AKT, and is associated with the regulation of cell proliferation, migration, and metastasis. It also interacts with β1 -adrenergic receptor, influencing cardiac function, and is related to lipid and cholesterol metabolism through its interaction with SR-B1 [2,3,4].

In mouse models, GIPC1 knockdown reduced MACC1-induced cell migration and invasion, and suppressed tumor growth and metastasis in mice transplanted with MACC1-overexpressing CRC cells, indicating its role in cancer metastasis [1]. In gastric cancer, GIPC1 knockdown blocked the PDGFR/PI3K/AKT signaling pathway, inhibiting cell proliferation and migration, while overexpression had the opposite effects [2]. GIPC1 cKO mice showed spontaneous cardiac hypertrophy, fibrosis, and systolic dysfunction, while AAV9-mediated GIPC1 overexpression attenuated isoproterenol-induced pathological cardiac remodelling in mice [3].

In conclusion, GIPC1 is crucial in processes like cancer metastasis, cell proliferation, migration, and cardiac function. Studies using gene knockout and overexpression models in mice have revealed its role in cancer and cardiac diseases, providing insights into potential therapeutic targets for these conditions.
