    basic FUNCTION
  • enabling kinesis to transport dendritic proteins such as AMPA receptor subunit GLUR2
  • required for cell-matrix interactions during early embryonic development
  • may play a role as a localized scaffold for the assembly of a multiprotein signaling complex and as mediator of the trafficking of its binding partners at specific subcellular location in neurons
  • playing an important role in dendrite morphogenesis by serving as an adaptor protein for kinesin-dependent transport of EPHB receptors to dendrites
  • binds to and regulates both the trafficking and membrane organization of a large number of transmembrane proteins (Long 2008)
  • previously unidentified role for AMPA-R-GRIP1-exocyst protein complexes in activity-dependent AMPA-R trafficking
  • may serve to organize macromolecular complexes, linking AMPA-Rs and other membrane proteins to the cytoskeleton and membrane trafficking and signal transduction pathways
  • multi-PDZ domain-containing protein that interact with the C-termini of AMPA-R GRIA2 and GRIA3 subunits
  • regulatory role for GRIP1 during microtubule-based transport and suggest a crucial function for 14-3-3 proteins in controlling kinesin-1 motor attachment during neuronal development
  • essential role of GRIP1-mediated AMPAR trafficking during inactivity-induced synaptic scaling
    signaling neurotransmission
    a component
  • GLUR2/GRIP1 complex
  • ephrin B1 EFNB1/GRIP1 complex
  • kinesin/GRIP1 complex
  • homomultimers or heteromultimers with GRIP2
  • forms a ternary complex with GRIA2 and CSPG4
    small molecule
  • EFNB1 and EFNB3
  • kinesin
  • GLUR2
  • DIP2(coactivation of transcription)
  • required for the deposition of both FRAS1 and FREM2 on the basement membrane, possibly through interactions with the cytoplasmic tails of these proteins
  • interacting with SUV420H1 (GRIP1-associated “secondary” cofactor for GR (glucocorticoid receptor), and active modulator of hormone-dependent gene expression) (Chinenov 2008)
  • interacting with FRAS1 (provides a mechanistic explanation of the link between GRIP1 and the Fraser syndrome but may also serve as a foundation for searching for potential mutations in GRIP1 that could lead to the Fraser syndrome) (Long 2008)
  • bind to the C-termini of AMPA-R GRIA2 and GRIA3 subunits
  • CREB1 mediates the PRKAA-stimulated degradation of GRIP1 through protein-protein interaction and stimulation of proteasomal degradation of ubiquitinated GRIP1
  • TRIP6-GRIP1-MYO6 interaction and its regulation on F-actin network play a significant role in dendritic morphogenesis
  • activity-dependent trafficking of GRIP1 to synaptic sites drives the forward trafficking and enhanced synaptic accumulation of GRIA2-containing AMPAR during synaptic scaling up
