Glial Fibrillary Acidic Protein (GFAP, ALXDRD) is a major filament protein in astrocytes, and is frequently used as a marker to distinguish astrocytes from other glial cells, although it is also found in certain kidney, testes, pancreas, and liver cells. GFAP is part of a small family of intermediate filament proteins that are involved in cytoskeleton structure and function. GFAP helps in maintaining the blood-brain barrier, participates in mitosis, damage repair, and cell-cell communication. One GFAP mutation leads to the creation of Rosenthal fibers, a hallmark of Alexander disease. It is involved or implicated in Down's syndrome, depression, traumatic brain injury, neurodegeneration, and stroke.
