CAMTA1 and malignant colon neoplasm: It encodes synthetic Calmodulin Binding Transcription Activator 1 (CAMTA1), which could inhibit the proliferation of various tumor cells, including breast cancer, colon cancer, pheochromocytoma, etc. Current research on the CAMTA1 protein has focused on its role in the pathogenesis of Epithelioid hemangioendothelioma (EHE), a malignant tumor of vascular endothelial cell origin.
