Descripción de destino

Glial fibrillary acidic protein (UniProt: P14136; also known as GFAP) is encoded by the GFAP gene (Gene ID: 2670) in human. GFAP is a class-III intermediate filament that serves as a cell-specific marker that can distinguish astrocytes from other glial cells. GFAP is not detected outside the central nervous system. It is expressed in cells that lack fibronectin. GFAP is a good marker of astroglial injury where its levels are consistently upregulated. GFAP levels are also shown to be upregulated with age in rodents and humans. Hence, it can serve as a surrogate marker of aging in the brain. GFAP has a relatively slow metabolic turnover rate, which is consistent with its structural role. GFAP is composed of three distinct regions: an N-terminal head region, a central ROD region, and a C-terminal tail region. The ROD regions are highly conserved among intermediate filament proteins. However, the size and amino acid sequences of the head and tail regions can vary widely. Three different isoforms of GFAP have been described that are produced by alternative splicing. Mutations in GFAP gene are known to cause Alexander disease that is characterized by progressive failure of central myelination, usually leading to death within the first decade. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
