Inactivation of ABL1 with brain-penetrant nilotinib conferred neuroprotective autophagy in mouse models of PD 153 . PubMed:30116051
ABL1 is overactivated in AD and tauopathies such as FTD 152 . PubMed:30116051
ABL1 is overactivated in AD and tauopathies such as FTD 152 . PubMed:30116051
Tyrosine-protein kinase ABL1 is a proto- oncogene that negatively regulates autophagy, partly acting upstream of the RAC serine/threonine-protein kinase (AKT)–mTORC1 axis. PubMed:30116051
Tyrosine kinases target Y18 [fyn, (79)] and Y394 [abl, (31)]. PubMed:17493042
The single kinase and sequential kinase-catalyzed Fc-phosphorylations points to dramatic changes around the Fc group in the Fc-phosphorylated tau films. Additional surface characterization of the Fc-tau films by time-of-flight secondary ion-mass spectrometry and X-ray photoelectron spectroscopy revealed that Fc-phosphorylations influence the tau orientation and conformation on surfaces.

The responsible kinases include 1) proline-directed protein kinases (PDPKs) targeting SP or TP motifs [e.g., GSK3b, cyclindependent kinase (CDK)-5, and MAPKs]; 2) non–proline directed protein kinases targeting KXGS-motifs [e.g., PKA, microtubule affinity-regulating kinase and synapses of the amphid defective (SADK)]; 3) protein kinases specific for tyrosines (e.g., Src, Lck, Syk, Fyn, and c-Abl kinase) (91). PubMed:29191965
In addition, tau can be phosphorylated by tyrosine kinases such as the SRC family members LCK, SYK and FYN at Tyr18, and the ABL family members ARG and ABL1 at Tyr394 (REF. 45). PubMed:26631930
