glial fibrillary acidic protein

a cytoskeletal protein of 51 kD found in fibrillary astrocytes; stains for this protein are frequently used to assist in the differential diagnosis of neurologic lesions.
Farlex Partner Medical Dictionary © Farlex 2012


A gene on chromosome 17q21 that encodes a major class-III intermediate filament protein of mature astrocytes, which serves as a marker (in histopathology) to distinguish astrocytes from other glial cells, both during development and in tumour diagnostics.

glial fibrillary acidic protein

Abbreviation: GFAP
An intermediate filament found only in astrocytes and astroglial cells. It forms part of the skeletal structure of neurons. Abnormalities in GFAP are found in a variety of neurological diseases, including Alzheimer's disease, Creutzfeldt-Jakob disease, and some brain tumors.
