SFKs, which participate in the development of tauopathies to a lesser degree than other more studied tau kinases [89], phosphorylate tau at Tyr 18, 29, 197, 310, and 394, which are related to tauopathies, and at residues that are phosphorylated under physiological conditions, such as Tyr 394 [89]. Here, MAPT is linked to tauopathy.
