| Post Translational Modifications | Polyubiquitinated. Requires functional TRAF6 and may provoke SQSTM1-dependent degradation by the proteasome. Phosphorylated at various serine and threonine residues in S-P or T-P motifs by proline-directed protein kinases (PDPK1, CDK1, CDK5, GSK3, MAPK) (a few sites per protein in interphase, more in mitosis), and at serine residues in K-X-G-S motifs by MAP/microtubule affinity-regulating kinase (MARK1, MARK2, MARK3, MARK4), causing detachment from microtubules, and their disassembly. Fetal Tau is much more phosphorylated than adult Tau. Phosphorylation at Ser-573 by BRSK1 and BRSK2 in neurons affects ability to bind microtubules and plays a role in neuron polarization. Phosphorylated by PHK. Dephosphorylation at several serine and threonine residues by the serine/threonine phosphatase PPP5C. Phosphorylation at Ser-204 by SGK1 mediates microtubule depolymerization and neurite formation in hippocampal neurons. |
| Function | Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. |
