MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the homer family of dendritic proteins. Members of this family regulate group 1 metabotrophic glutamate receptor function. The encoded protein is a postsynaptic density scaffolding protein. Alternative splicing results in multiple transcript variants. Two related pseudogenes have been identified on chromosome 14. [provided by RefSeq, Jun 2011]
PHENOTYPE: Homozygous mutants exhibit an increase in intracellular calcium concentration and in the frequency of intracellular calcium oscillations in pancreatic acinar cells. [provided by MGI curators]
