產(chǎn)品介紹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.

星形膠質(zhì)細(xì)胞標(biāo)志物 （Astrocyte Marker）

GFAP是一個(gè)56kDa的中間絲蛋白（intermediate filament，IF），在中樞神經(jīng)系統(tǒng)發(fā)育期是一個(gè)特異性的標(biāo)志物，以區(qū)別星形細(xì)胞和其它膠質(zhì)細(xì)胞。GFAP表達(dá)在皮層和海馬,急、慢性皮質(zhì)酮治療時(shí)表達(dá)減少。

GFAP可以和人、大鼠、小鼠的GFAP反應(yīng)，在正常和腫瘤性的星形膠質(zhì)細(xì)胞陽(yáng)性表達(dá)，而神經(jīng)節(jié)細(xì)胞、神經(jīng)元、成纖維細(xì)胞、少突膠質(zhì)細(xì)胞和這些細(xì)胞來(lái)源的腫瘤細(xì)胞陰性表達(dá)，主要用于星形膠質(zhì)瘤等中樞神經(jīng)系統(tǒng)腫瘤的診斷和鑒別診斷,GFAP的缺乏可導(dǎo)致AD病。
