HMDB Protein ID CDBP02947
Secondary Accession Numbers Not Available
Name Homer protein homolog 1
Description Not Available
Synonyms
  1. Homer-1
Gene Name HOMER1
Protein Type Enzyme
Biological Properties
General Function Cell cycle control, cell division, chromosome partitioning
Specific 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 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
