Annotated paper:Chen PJ, et al. "AChRs Are Essential for the Targeting of Rapsyn to the Postsynaptic Membrane of NMJs in Living Mice" J Neurosci. 2016 May 25;36(21):5680-5 PMID:27225759
Figure(s):figure 1-4
Annotation description:Co-localizes with acetylcholine receptors (AChRs) in mouse NMJ, fluorescence imaging + fig4. Rabsyn is surface expressed, can be deleted/rescued by mutation of AChR interacting domain in myoblasts.

"Altogether, these results strongly suggest that AChRs serve as a mediator for the targeting and association of rapsyn with the postsynaptic membrane at synaptic sites."
