J Neurosci. 2002;22:3493-503 pubmed..We suggest that pABP-L and ABP-L provide, respectively, synaptic and intracellular sites for the anchorage of AMPA receptors during receptor trafficking to and from the synapse. ..

- Perez Olle R, Lopez Toledano M, Liem R. The G336S variant in the human neurofilament-M gene does not affect its assembly or distribution: importance of the functional analysis of neurofilament variants. J Neuropathol Exp Neurol. 2004;63:759-74 pubmed..Our data suggest that if the G336S variant is involved in the development of PD, it does not appear to be due to defects in the assembly and distribution of NFs. ..
