Description
Function: 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 CENTG1. 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.Subcellular location: Cytoplasm. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density. Cell junction, synapse. Note: Postsynaptic density of neuronal cells. Isoform 1 inhibits surface expression of GRM5 causing it to be retained in the endoplasmic reticulum. Also known as: Home1, Homer protein homolog 1, SYN47.
Immunogen
A synthetic peptide from the internal region of human HOMER1 conjugated to blue carrier protein was used as the antigen. The peptide is homologous in mouse, rat, monkey and xenopus.
