Disease relevance of Galr2

 

High impact information on Galr2

  • GALR2-EGFP on the plasma membrane was internalized within 5-10 min after treatment with galanin or AR-M1896, a selective GALR2 agonist, with a dramatic reduction in plasma membrane localization and appearance in intracellular vesicles [2].
  • Taken together these findings indicate that GALR2 undergoes constitutive endocytosis and recycling and that both ligand-independent and ligand-dependent internalization use the clathrin-dependent endocytic recycling pathway [2].
  • GAL-R2 would appear to be expressed only in the anterior pituitary and hypothalamus [3].
  • The GALR2 cDNA encoded a protein of 372 amino acids exhibiting 38% amino acid identity with rat GALR1 [4].
  • VM cultures expressed GALR1, GALR2, and GALR3 receptor mRNA [5].
