WebbThe SHANK3 gene, located in chromosome 22q13.3, encodes for a scaffolding protein found in the postsynaptic density complex of excitatory synapses, where it binds to neuroligins and to actin, affecting actin polymerization, growth cone motility, dendritic spine morphology, and synaptic transmission ( Durand et al., 2011 ). Webb6 jan. 2016 · Shank3 is a very complex gene at the transcript level because of multiple intragenic promotors and alternative splicing (Wang et al., 2011b, Wang et al., 2014b).Both InsG3680 and R1117X mutations are in exon 21, which is common to most if not all isoforms, and the two mutations were separated by only 325 nucleotides (Figure 1 A).For …

We have generated and characterized both isoform specific and complete Shank2 and Shank3 mutant mice.
WebbThese findings show that deficiency of the autism-associated Shank3 gene can impair mGluR5-Homer scaffolding, resulting in cortico-striatal circuit abnormalities which underlie deficits in learning and ASD-like behaviors. These data suggest causal links between genetic, molecular, and circuit mechanisms underlying the pathophysiology of ASDs.
