Moreover, the serine 616 (Ser616) site of Drp1 is known to be phosphorylated by cyclin‐dependent kinase 1 (Cdk1), calmodulin‐dependent protein kinase II (CaMKII), and ERK in cardiomyocytes, fibroblasts, and colorectal cancer, and this site phosphorylation results in excessive mitochondrial fission and cell apoptosis [12]. The gene discussed is CDK1; the disease is colorectal cancer.
