Hyperphosphorylated tau
Hyperphosphorylated tau disassembles microtubules and sequesters normal tau, MAPT 1 (microtubule associated protein tau 1), MAPT 2 and ubiquitin into tangles of PHFs. This insoluble structure damages cytoplasmic functions and interferes with axonal transport , which can lead to cell death. Meer weergeven The tau proteins (abbreviated from tubulin associated unit ) are a group of six highly soluble protein isoforms produced by alternative splicing from the gene MAPT (microtubule-associated protein tau). They have roles … Meer weergeven Microtubule stabilization Tau proteins are found more often in neurons than in non-neuronal cells in humans. One of tau's main functions is to modulate … Meer weergeven Six tau isoforms exist in human brain tissue, and they are distinguished by their number of binding domains. Three isoforms have three binding domains and the other three have four binding domains. The binding domains are located in the carboxy-terminus Meer weergeven Tau protein has been shown to interact with: • Alpha-synuclein, • FYN, • Proto-oncogene tyrosine-protein kinase Src • S100B, and Meer weergeven In humans, the MAPT gene for encoding tau protein is located on chromosome 17q21, containing 16 exons.
