We describe a new human isoform, GFAP , of the intermediary filament protein GFAP (glial fibrillary acidic protein). GFAP mRNA is the result of alternative splicing and a new polyadenylation signal, and thus GFAP has a new C-terminal protein sequence. This provides GFAP with the capacity for specific binding of presenilin proteins in yeast and in vitro. Our observations suggest a direct link be...
Glial fibrillary acidic protein (GFAP) is an intermediate filament protein expressed predominantly in astrocytes. The study of its expression in the astrocyte lineage during development and in reactive astrocytes has revealed an intricate relationship with the expression of vimentin, another intermediate filament protein widely expressed in embryonic development. these findings suggested that v...
Glial fibrillary acidic protein (GFAP) is the main component of intermediate filaments in astrocytes. To assess its function in astrocyte swelling, we compared astrocyte membrane properties and swelling in spinal cord slices of 8- to 10-day-old wild-type control (GFAP(+/+)) and GFAP-knockout (GFAP(-/-)) mice. Membrane currents and K(+) accumulation around astrocytes after a depolarizing pulse w...
After traumatic brain injury (TBI), glial fibrillary acidic protein (GFAP) and other brain-derived proteins and their breakdown products are released into biofluids such as CSF and blood. Recently, a sandwich ELISA was constructed that measured GFAP concentrations in CSF or serum from human mild-moderate TBI patients. The goals of the present study were to characterize the same two antibodies u...
Glial fibrillary acidic protein (GFAP) is a M(r) 50,000 intracytoplasmic filamentous protein that constitutes a portion of, and is specific for the cytoskeleton of the astrocyte. GFAP appears to stabilize the astrocyte's cytoskeleton, and helps maintain normal astrocyte cell shape through complex interactions between it and the nuclear and plasma membranes. A critical observation from histopath...
The epithelium of the mouse lens stains intensely with antisera to glial fibrillary acidic protein (GFAP). A protein co-migrating with GFAP and immunoreactive with antisera to GFAP can be demonstrated in lens epithelium protein extracts by immunoblots. GFAP has previously been considered unique to cells of neural origin, but this study demonstrates that ectodermally derived cells express GFAP o...
A significant proportion of human malignant gliomas exhibit amplification, overexpression, or mutations of the epidermal growth factor receptor (EGFR). To define the functional role(s) of the EGFR in the pathogenesis of gliomas, we established transgenic mice that express both wild-type (wt) and mutant (EGFRvIII) EGFR molecules using the human glial fibrillary acidic protein (GFAP) promoter. Bo...
Glial fibrillary acidic protein (GFAP) is a A/, 50,000 intracytoplasmic filamentous protein that constitutes a portion of, and is spécifiefor the cytoskeleton of the astrocyte. GFAP appears to stabilize the astrocyte's cytoskeleton, and helps maintain normal astrocyte cell shape through complex interactions between it and the nuclear and plasma membranes. A critical observation from histopatho...
Glial fibrillary acidic protein (GFAP) is the main astrocytic intermediate filament (IF). GFAP splice isoforms show differential expression patterns in the human brain. GFAPδ is preferentially expressed by neurogenic astrocytes in the subventricular zone (SVZ), whereas GFAP(+1) is found in a subset of astrocytes throughout the brain. In addition, the expression of these isoforms in human brain ...
