The receptor-interacting protein kinase 1 (RIPK1) is an essential signaling molecule in pathways for cell survival, apoptosis, and necroptosis. We report here that RIPK1 is upregulated in human colorectal cancer and promotes cell proliferation when overexpressed in a colon cancer cell line. RIPK1 interacts with mitochondrial Ca2+ uniporter (MCU) to promote proliferation by increasing mitochondrial Ca2+ uptake and energy metabolism. The ubiquitination site of RIPK1 (RIPK1-K377) was critical for this interaction with MCU and function in promoting cell proliferation. These findings identify the RIPK1-MCU pathway as a promising target to treat colorectal cancer.Significance: RIPK1-mediated cell proliferation through MCU is a central mechanism underlying colorectal cancer progression and may prove to be an important therapeutic target for colorectal cancer treatment.
