Description


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.

Gene editing strategy
A target vector was designed to insert iCre-WPRE-PA cassette into mouse endogenous genes 5 'UTR downstream of GFAP. The targeting vector was electroporated into C57BL/6-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and resulted chimeric mice. These mice were maintained on a C57BL/6 background.
Phenotype analysis

In situ hybridization in hippocampal CA1 area to confirm µR selective 

deletion from µRGFAP-/- mice with probes of µR mRNA (red), 

GAD2/ GFAP/vGlut1 mRNA (green), and DAPI nucleus staining (blue).
