Figure(s):Fig. 1C, 4, 5B
Annotation description:tPA localizes to postsynapes opposite to synapsin (Fig. 1C) in primary hippocampal neurons and is co-enriched with PSD-95 in synaptoneurosome preparations (Fig. 5B).

- Fig.4: Expression of tPA mRNA in dendrite
Figure shows that the tPA protein is expressed by and therefore localized to the denditic compartment. The synaptic localization show in Fig.1 is therefore (at least) postsynaptic.

Evidence for activity-dependent release is provided by the study by Lochner et al. (2005) PMID 16555239. Accordingly the site of action is supposedly the synaptic cleft or the perisynaptic extracellular matrix.

Additional literature:Supplemental table S1 contains 492 proteins of the PSD fraction identified either by 2D gel electrophoresis followed by MS/MS or by LC-MS/MS. tPA was among these identified proteins. @ PMID:14720225

This paper shows recombinant tPA in dendritic spines of mature hippocampal neurons in culture (Fig. 2, 3). Upon K+-induced depolarization recombinant tPA is released (Fig. 6) @ PMID:16555239
