Recombinant human tag-free Tau-441 was co-expressed with DYRK1A in E. coli cells, phosphorylated by DYRK1A in vivo and in vitro, then the purified protein was chemically biotinylated in vitro.

Overview:
Tau-441 or Tau-F is a member of the Tau family of proteins which function to stabilize the microtubules by binding to them. Tau proteins are subject to phosphorylation and this phenomenon regulates the association of the Tau protein with the microtubules (1). 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 (betaAPP), 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 microtubules disintegration and collapsing of the neuronal transport system (2).
