Opis

Opis ogólny

Research area: Neuroscience

Tau-441 is a member of the Tau family of proteins. Tau is a family of neuronal microtubule-associated proteins. Six isoforms have been found that differ from each other in having either 3 or 4 binding repeats (R) of 31-32 amino acids, and from zero to 3 amino terminal inserts (N) of 29 amino acids each.

Zastosowanie

Tau-441 human has been used to study the tau uptake by human bronchial epithelial cells (HBEC).

Działania biochem./fizjol.

Tau proteins are mainly expressed in the neurons of the central nervous system where they exert a role in stabilizing microtubules, key components of axonal transport, as well as in signal transduction. Tau proteins are subject to phosphorylation, which regulates their association with the microtubules. Deposits of Alzheimer′s disease AD-associated proteins, such as hyperphosphorylated Tau, as well as other shared misfolded proteins, such as beta-amyloid precursor protein (beta-APP), ubiquitin, and various chaperones and protein kinases, are thought to play a pathologic role in the cognitive decline and muscular failure. Malfunctioning of Tau proteins is associated with microtubule disintegration and collapsing of the neuronal transport system. Among other diseases, Tau forms in cerebrospinal fluid are considered a reliable biomarker for progressive supranuclear palsy, where the levels of Tau forms ratio were significantly reduced.
