Evidences p(MGI:Mapt, var("p.Ala152Thr")) to p(MGI:Mapt)

In this study, we analyzed the contribution of three different types of autophagy, macroautophagy, chaperone-mediated autophagy, and endosomal microautophagy to the degradation of tau protein variants and tau mutations associated with this agerelated disease. We have found that the pathogenic P301L mutation inhibits degradation of tau by any of the three autophagic pathways, whereas the risk-associated tau mutation A152T reroutes tau for degradation through a different autophagy pathway

An increase in overall tau levels has been observed in brains from patients bearing either P301L or A152T mutation on tau (Torres et al., 1998)

Taken together, our in vitro and cell-based studies argue that these two point mutations, A152T and P301L, reduce the normal degradation of tau by CMA, although the P301L mutation has a more pronounced inhibitory effect

In summary, when comparing the pathogenic tau mutation P301L with the risk-associated mutation A152T, we found that both reduced normal turnover of tau by autophagy, but that the effect of the P301L mutation was more pronounced (summarized in Fig. 2g and Fig. S6, Supporting information)
