Description
Product Characteristics:
Postsynaptic density scaffolding protein. Binds and cross-links cytoplasmic regions of GRM1, GRM5, ITPR1, DNM3, RYR1, RYR2, SHANK1 and SHANK3. By physically linking GRM1 and GRM5 with ER-associated ITPR1 receptors, it aids the coupling of surface receptors to intracellular calcium release. May also couple GRM1 to PI3 kinase through its interaction with AGAP2. Isoforms can be differently regulated and may play an important role in maintaining the plasticity at glutamatergic synapses.
Subcellular location: Cytoplasm, Cell membrane, Extracellular matrix
Synonyms: Cupidin, HOME2_HUMAN, HOMER 2, HOMER 2A, HOMER 2B, Homer homolog 2 Drosophila, Homer homolog 3, Homer neuronal immediate early gene 2, Homer protein homolog 2, Homer-2, Homer2, HOMER2A, HOMER2B, Vesl 2, Vesl2.
Target Information: 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.
