General annotation (Comments)
| Function | Seems to be an adapter protein in the postsynaptic density (PSD) of excitatory synapses that interconnects receptors of the postsynaptic membrane including NMDA-type and metabotropic glutamate receptors via complexes with GKAP/PSD-95 and Homer, respectively, and the actin-based cytoskeleton. May play a role in the structural and functional organization of the dendritic spine and synaptic junction. |
| Subunit structure | May homomultimerize via its SAM domain By similarity. Interacts with DLGAP1/GKAP, MGLUR1A, MGLUR5 C-termini via its PDZ domain By similarity. Interacts with HOMER1, HOMER2, HOMER3 and CCTN/cortactin SH3 domain By similarity. Is part of a complex with DLG4/PSD-95 and DLGAP1/GKAP. Interacts with DBNL By similarity. Interacts with BAIAP2. |
| Subcellular location | CytoplasmBy similarity. Cell junction › synapseBy similarity. Cell junction › synapse › postsynaptic cell membrane › postsynaptic densityBy similarity. Note= Postsynaptic density of neuronal cells By similarity. |
| Tissue specificity | Expressed in the cerebral cortex and the cerebellum. |
| Involvement in disease | A chromosomal aberration disrupting SHANK3/PSAP2 is responsible for the clinical features of chromosome 22q13.3 deletion syndrome [MIM:606232]. Translocation t(12;22)(q24.1;q13.3) with APPL2/DIP13B. The phenotype is characterized by neonatal hypotonia, global developmental delay, normal to accelerated growth, absent to severely delayed speech, autistic behavior and minor dysmorphic features. Defects in SHANK3 are a cause of autism spectrum disorders (ASD). ASD are characterized by impairments in reciprocal social interaction and communication as well as restricted and stereotyped patterns of interest and activities. ASD include forms with moderate to severe cognitive impairment and milder forms with higher cognitive ability (Asperger syndrome). |
| Sequence similarities | Contains 6 ANK repeats. Contains 1 PDZ (DHR) domain. Contains 1 SAM (sterile alpha motif) domain. Contains 1 SH3 domain. |
