GFP is an intermediate filament. GFP and vimentin are linked to the same filament network, they are localized in the same filaments. mRNAs encoding the glial intermediate filament protein are spatially dispersed in the glial cell cytoplasm close to the location of the glial filaments. Description: Bovine spinal cord. Alternative Names: Glial Fibrillary Acid Protein antibody, Glial Filament Protein, Glial marker protein, GFAP protein
