Previously we reported that Syt11 regulates multiple membrane trafficking pathways in neurons and glia. However, the regulation of Syt11 degradation remains largely unknown. As the ubiquitin-proteasome pathway (UPP) plays crucial roles in protein degradation and quality control, we investigated UPP-dependent Syt11 degradation in this study. We found that Syt11 is a short-lived protein with a half-life of 1.49 h in the presence of a protein synthesis inhibitor cycloheximide and is mainly degraded by UPP in neurons. The degradation was further accelerated under sustained neuronal activity and was parkin-dependent. Interestingly, Syt11 had a faster turnover in astrocytes with a half-life of 0.58 h, and UPP partially contributed to its degradation. Mechanical stress applied on astrocytes by hypoosmotic treatment led to reduced Syt11 protein level but increased parkin level. However, the degradation of Syt11 was parkin-independent under both isoosmotic and hypoosmotic condition. Altogether, our results revealed active and distinct proteolytic regulation of Syt11 in neurons and astrocytes."xsd:string |
