5. Comparison of the distributions of tau pTyr18 and double-phosphorylated Syk in the transgenic mouse brain and human hippocampus showed that the phosphorylation of tyrosine 18 in tau already occurs at an early stage of tauopathy and increases with the progression of neurodegeneration. Syk appears unlikely to be a major kinase that phosphorylates tyrosine 18 of tau at the early stage of tauopathy. PMID: 28919467

21. dephosphorylation of Tyr(P)(346) may be considered an important "checkpoint" in the regulation of Syk activation process.

PMID: 27609517
22. These studies define a pathologic role for myeloid Syk signaling in renal ischemia/reperfusion injury PMID: 27322771
