| Function | Under physiological conditions, CREB1 maintains cellular survival, proliferation, anti-inflammatory immune responses and modulates the development of the nervous system by serving a neuroprotective role. Under pathological conditions, increased levels of CREB1 is associated with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin’s lymphoma, chronic lymphatic leukemia (CLL), melanoma, hepatocellular, renal cell, ovarian, prostate, lung, gastric, esophageal, pancreatic, and breast tumors. CREB1 is also involved in the aging process by regulating the downstream signals of mitochondria dysfunction. |
