Application Abreviews Notes
Flow Cyt 1/10 - 1/50. ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
IHC-P 1/10 - 1/50. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/1000. Predicted molecular weight: 40 kDa.


  • 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. Isoforms can be differently regulated and may play an important role in maintaining the plasticity at glutamatergic synapses.
  • Sequence similarities
    Belongs to the Homer family.
    Contains 1 WH1 domain.
  • Domain
    The WH1 domain interacts with the PPXXF motif in GRM1, GRM5, RYR1, RYR2, ITPR1, SHANK 1 and SHANK3.
  • Cellular localization
    Cytoplasm. Cell junction > synapse > postsynaptic cell membrane > postsynaptic density. Cell junction > synapse. Postsynaptic density of neuronal cells.
