    basic FUNCTION
  • receptor for corticotropin releasing factor
  • may be playing a central anxiolytic role at least time in mice
  • coupling with Gs alpha protein and activating adenylate cyclase
  • functioning as a local negative regulator of glucose uptake in skeletal muscle and encouraging exploration of the possibility that suppression of the UCN 2/CRHR2 pathway may provide benefits in insulin-resistant states such as type 2 diabetes
  • play a facilitatory role in the non-clathrin-, non-caveolae-mediated endocytosis and intracellular signal transduction of urocortin (Tu 2007)
  • CRHR2-positive neurons in the posterior medial amygdala are involved in the neural response to social defeat
  • activation of CRHR2 inhibits P-currents in Purkinje neurons via G(o)alpha-dependent PLC/PKCepsilon pathway, which might contribute to its physiological functions in the cerebellum
  • its activation could inhibit MAPK8 and AKT1 phosphorylation to suppress the secretion of VEGFA in small cell lung carcinoma cells
  • novel role for UCN3 and CRHR2 related to the processing of social cues and to the establishment of social memories
  • CRHR1 and CRHR2 differentially modulate the dendritic growth of hippocampal neurons

    small molecule
    protein
  • binds to urocortin I, II and III
  • interacting with HPGD (mediate divergent effects on PGDH expression, and this may provide a precise regulation of PGs levels from chorion to myometrium during pregnancy)
  • CRHR2 activation decrease DPYSL4 expression in hippocampal neurons via a mechanism that is dependent on PLC/PKC signaling pathways
  • although not amidated, UCN2 prohormone purified from overexpressing lines activated CRHR2
  • cell & other
