Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables ionotropic glutamate receptor binding activity and synaptic receptor adaptor activity. A structural constituent of postsynaptic density. Involved in several processes, including dendritic spine morphogenesis; learning or memory; and regulation of signal transduction. Acts upstream of or within negative regulation of actin filament bundle assembly. Located in dendritic spine; excitatory synapse; and plasma membrane. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynaptic density. Colocalizes with postsynaptic membrane. Is expressed in cerebral cortex; frontal cortex; and neocortex region. Orthologous to human SHANK1 (SH3 and multiple ankyrin repeat domains 1). PHENOTYPE: Homozygous mutation of this gene results in smaller pyramidal neuron dendritic spines, smaller and thinner postsynaptic density of central excitatory synapses, weaker synaptic transmission, increased anxiety-related behavior, and impaired contextual fearmemory, but enhanced spatial learning.
