SHANK3
SH3 and multiple ankyrin repeat domains 3 (Shank3), also known as proline-rich synapse-associated protein 2 (ProSAP2), is a protein that in humans is encoded by the SHANK3 gene on chromosome 22.[1] Additional isoforms have been described for this gene but they have not yet been experimentally verified.
Function
This gene is a member of the Shank gene family. Shank proteins are multidomain scaffold proteins of the postsynaptic density that connect neurotransmitter receptors, ion channels, and other membrane proteins to the actin cytoskeleton and G-protein-coupled signaling pathways. Shank proteins also play a role in synapse formation and dendritic spine maturation.[2]
Clinical significance
Mutations in this gene are associated with autism spectrum disorder. This gene is often missing in patients with 22q13.3 deletion syndrome,[3] although not in all cases.[4]
Interactions
SHANK3 has been shown to interact with ARHGEF7.[5]
Mouse models
Mouse models of Shank3 include N-terminal knock-outs[6][7] and a PDZ domain knock-out[8] all of which also show social interaction deficits and variable other phenotypes. Most of the these mice are homozygous knock-outs whereas all the human Shank3 mutations have been heterozygous.
