Disease relevance of Grip1

 

High impact information on Grip1

 

Biological context of Grip1

 

Anatomical context of Grip1

  • A clonal cell line prepared from immortalized GRP cells, termed GRIP-1, was also shown to retain the properties of a glial-restricted tripotential precursor [8].
  • ErbB1 receptor ligands attenuate the expression of synaptic scaffolding proteins, GRIP1 and SAP97, in developing neocortex [9].
  • Constitutive uterine mRNA expression of switch protein for antagonist (SPA), SRC-1, GRIP1, RAC3, RIP140, and p300 mRNAs was observed in control uteri, and treatment with ER ligands did not alter coactivator mRNA levels [10].
 

Associations of Grip1 with chemical compounds

  • NMDA receptors interact via their NR2 subunits with PSD-95/SAP90 family proteins, whereas AMPA receptors bind via their GluR2/3 subunits to glutamate receptor-interacting protein (GRIP), AMPA receptor-binding protein (ABP), and protein interacting with C kinase 1 (PICK1) [5].
  • GRIP1 PDZ7 contains a closed carboxyl group-binding pocket and a narrow alphaB/betaB-groove that is not likely to bind to classical PDZ ligands [1].
  • The interaction between GRIP1 PDZ7 and a Ras guanine nucleotide exchange factor, GRASP-1, regulates synaptic distribution of AMPA receptors [1].
  • Differential cellular and subcellular localization of ampa receptor-binding protein and glutamate receptor-interacting protein [11].
  • 2. Grip strength and biochemical measurements, i.e. serum creatine phosphokinase (CPK) activity and creatine urinary excretion rate, together with histological studies, were performed in resting animals during a period of 14 days of PYR administration in a dose producing 20-30% whole blood acetylcholinesterase inhibition [12].
 

Physical interactions of Grip1

 

Other interactions of Grip1

  • Decline in SAP97 and GRIP1 levels was associated with increased abundance of lower molecular weight bands, suggesting degradation of these proteins [14].
  • Proteolysis of glutamate receptor-interacting protein by calpain in rat brain: implications for synaptic plasticity [15].
  • Using in situ hybridization we have examined the neuroanatomical distribution of the messenger RNAs (mRNAs) for two functionally distinct splice variants of Steroid Receptor Coactivator 1 (SRC-1/NCoA-1) and of Steroid Receptor Coactivator 2 (SRC-2/NCoA-2/GRIP-1/TIF-2) [16].
  • Such coactivators include three members of the 160 kDa proteins (p160s): SRC-1, TIF2/GRIP1, and p/CIP/RAC3/ACTR/AIB1/TRAM-1 [17].
