研究背景
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. Isoform 1 regulates the trafficking and surface expression of GRM5. Isoform 3 acts as a natural dominant negative, in dynamic competition with constitutively expressed isoform 1 to regulate synaptic metabotropic glutamate function. Isoform 3, may be involved in the structural changes that occur at synapses during long-lasting neuronal plasticity and development. Forms a high-order complex with SHANK1, which in turn is necessary for the structural and functional integrity of dendritic spines (By similarity). Negatively regulates T cell activation by inhibiting the calcineurin-NFAT pathway. Acts by competing with calcineurin/PPP3CA for NFAT protein binding, hence preventing NFAT activation by PPP3CA.

Note: Isoform 1 inhibits surface expression of GRM5 causing it to be retained in the endoplasmic reticulum.
Tetramer; this tetrameric structure is critical for forming the high-order complex with SHANK1, which in turn is necessary for the structural and functional integrity of dendritic spines (By similarity). Interacts with GRM1, GRM5, ITPR1, DNM3, RYR1, RYR2 and SHANK3. Interacts with IFT57 and OPHN1. Isoform 1 encodes a coiled-coil structure that mediates homo- and heteromultimerization. Interacts with SHANK1; forms high-order polymerized complex with a mesh-like network structure, at least composed of SHANK1, HOMER1 and DLGAP1; the complex formation is SHANK1 multimerization dependent.Interacts with SHANK1; forms high-order polymerized complex with a mesh-like network structure, at least composed of SHANK1, HOMER1 and DLGAP1; the complex formation is SHANK1 multimerization dependent (By similarity). Interacts with NFATC4.
The WH1 domain interacts with the PPXXF motif in GRM1, GRM5, RYR1, RYR2, ITPR1, SHANK 1 and SHANK3. The coiled-Coil domain forms an antiparallel tetrameric arrangement (By similarity).
Belongs to the Homer family.
