产品介绍 This gene encodes one of the major intermediate filament proteins of mature astrocytes. It is used as a marker to distinguish astrocytes from other glial cells during development. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Oct 2008]

Function:
GFAP, a class-III intermediate filament, is a cell-specific marker that, during the development of the central nervous system, distinguishes astrocytes from other glial cells.

Subunit:
Interacts with SYNM. Isoform 3 interacts with PSEN1 (via N-terminus).

Subcellular Location:
Cytoplasm. Note=Associated with intermediate filaments.

Tissue Specificity:
Expressed in cells lacking fibronectin.

Post-translational modifications:
Phosphorylated by PKN1.

DISEASE:
Defects in GFAP are a cause of Alexander disease (ALEXD) [MIM:203450]. Alexander disease is a rare disorder of the central nervous system. It is a progressive leukoencephalopathy whose hallmark is the widespread accumulation of Rosenthal fibers which are cytoplasmic inclusions in astrocytes. The most common form affects infants and young children, and is characterized by progressive failure of central myelination, usually leading to death usually within the first decade. Infants with Alexander disease develop a leukoencephalopathy with macrocephaly, seizures, and psychomotor retardation. Patients with juvenile or adult forms typically experience ataxia, bulbar signs and spasticity, and a more slowly progressive course.

Similarity:
Belongs to the intermediate filament family.

星形胶质细胞标志物 (Astrocyte Marker)

GFAP是一个56kDa的中间丝蛋白(intermediate filament,IF),在中枢神经系统发育期是一个特异性的标志物,以区别星形细胞和其它胶质细胞。GFAP表达在皮层和海马,急、慢性皮质酮治疗时表达减少。
GFAP可以和人、大鼠、小鼠的GFAP反应,在正常和肿瘤性的星形胶质细胞阳性表达,而神经节细胞、神经元、成纤维细胞、少突胶质细胞和这些细胞来源的肿瘤细胞阴性表达,主要用于星形胶质瘤等中枢神经系统肿瘤的诊断和鉴别诊断,GFAP的缺乏可导致AD病。
