Annotated paper:Wyszynski M, et al. "Interaction between GRIP and liprin-alpha/SYD2 is required for AMPA receptor targeting" Neuron. 2002 Mar 28;34(1):39-52 PMID:11931740
Figure(s):Fig. 5, Fig. 3
Annotation description:- Postembedding immunogold EM of adult rat cerebral cortex was performed using 254.2 anti-liprin2-antibody.

- Fig5B-C: EM images show the expression of gold particles adjacent to the postsynaptic membrane.

- Fig5E quantifies the distribution of gold particles relative to the postsynaptic membrane (value of 0). The high peak within 50 nm of the postsynaptic membrane is suggestive of liprin-alpha 2 being localized in close proximity to the postsynaptic membrane in the postsynaptic specialization.

- Fig. 3: Double immunofluorescence experiments demonstrated localization of liprin-alpha 2 with the postsynaptic protein GRIP along dendrites.
