In contrast, Pin1/PINN-1 (a DAPK interaction-partner and a peptidyl-prolyl isomerase involved in chronic neurodegenerative conditions) suppresses neurodegeneration in our excitotoxicity model. PubMed:25899010
Overexpression of UNC5B induces neuronal death by activating death-associated protein kinase (DAPK1) (19) via protein phosphatase 2A-mediated dephosphorylation of DAPK1 (20). PubMed:27068745
DAPK1-mediated increase in tau protein expression and stability were accompanied by increased Pin1 Ser71 phosphorylation. PubMed:24853415
DAPK1, but not its kinase deficient mutant (K42A), significantly increased human Aβ secretion in neuronal cell culture models. Moreover, knockdown of DAPK1 expression or inhibition of DAPK1 catalytic activity significantly decreased Aβ secretion. Furthermore, DAPK1, but not K42A, triggered Thr668 phosphorylation of APP, which may initiate and facilitate amyloidogenic APP processing leading to the generation of Aβ. PubMed:27094130

In this report, we describe a novel mechanism of action determined by the JunD component of AP-1, a factor enhancing cell survival in v-Src-transformed cells. We show that the loss of JunD results in the aberrant activation of a genetic program leading to cell death. This program requires the activation of the tumor suppressor death-associated protein kinase 1 (DAPK1). Since DAPK1 is phosphorylated and inhibited by v-Src, these results highlight the importance of this kinase and the multiple mechanisms controlled by v-Src to antagonize the tumor suppressor function of DAPK1.

Importantly, depletion of MARK1/2 reversed the inhibitory effect of DAPK on MT regrowth (Figure 5c, right panel). These results indicate that the DAPK–MARK signaling axis inhibits MT assembly and stability. PubMed:21311567

Furthermore, DAPK1-induced APP phosphorylation was suppressed when DAPK1 ΔDD was introduced (Fig. 4G), indicating that DAPK1 regulates Aβ secretion through APP Thr668 phosphorylation. PubMed:27094130

We showed previously that DAPK1 phosphorylates Ser71 in the catalytic active site of Pin1, thereby inhibiting its cellular function. PubMed:24853415
As shown in Figure 7a, compared with the vector control, DAPK1, but not DAPK1K42A, increased the phosphorylation of exogenous tau protein in HeLa cells, as detected by Thr231-specific (AT180), Ser262-specific, and Ser396-specific (PHF-13) antibodies that recognize specific tau phosphoepitopes and/or abnormal conformations specific to AD NFT. PubMed:24853415
These data suggest that tau hyperphosphorylation at Thr231, Ser262, and Ser396 by DAPK1 renders the cells more resistant to the kinase-induced apoptotic cell death, providing new insights into the tau-involved apoptotic abortion in the course of chronic neurodegeneration. PubMed:23948915

Furthermore, silencing of both MARK1 and MARK2 blocked DAPK-induced tau S262 phosphorylation (Figure 3e). More importantly, a decrease of pS262 tau, but not total tau, was observed in brain extracts derived from DAPK−/− mice, compared with that from DAPK+/+ mice (Figure 3f). These results strongly suggest a role of endogenous DAPK in stimulating the activity of endogenous MARK, which in turn phosphorylates tau in neurons. PubMed:21311567
