Annotation description:Using fluorescence microscopy, APPBP1 KO mice were found to have a smaller density of spines in hippocampal CA1 neurons. The neurons exhibited reduced post-tetanic potentiation values and deficits in the maintenance of LTP. In addition, NMJ from APPBP1 KO mice show smaller pre- and postsynaptic areas and decreased aposition as compared to wild type controls.

- The authors mention that APBB1 is a scaffold protein and show effects on spine density after perturbation. LTP is affected. Moreover, the NJM structure is perturbed. Because of the known scaffolding function I agree with the expert that it is likely that organizing the synaptic structure is the prinicpal role of APBB1 and that effects on LTP are a consequence of this.
