    text
  • GNAS and CCDC88A localize to EEA1 early endosomes
    • basic FUNCTION
  • putatively involved in secretory vesicle formation
  • involved in hormonal regulation of adenylate cyclase: activation of the cyclase in response to beta-adrenergic stimuli
  • proteolytically derived peptide (LSAL) antagonizing serotonergic receptor 5HT1RB
  • involved as modulators or transducers in various transmembrane signaling systems
  • primarily mediating the differential effects of parathyroid hormone on trabecular and cortical bone in osteoblasts
  • negatively regulating chondrocyte differentiation and acting as critical signaling mediator of the PTH/PTH-rP receptor in growth plate chondrocytes
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • composed of 3 units (beta, gamma and alpha chain containing the guanine nucleotide binding site)
    • INTERACTION
    DNA
    RNA
    small molecule nucleotide,
  • GTP
    • protein
  • ALEX1
  • GNAS facilitates EEA1 endosome maturation, limits EGFR signaling from EEA1 endosomes, and inhibits cell proliferation
  • GNAS facilitates dissociation of EEA1 from membranes, which is a key step in EEA1 endosome maturation and EGFR signal down-regulation
  • GNAS and CCDC88A functionally interact to facilitate endosome maturation, EGFR degradation, and down-regulation of EGFR proliferative signaling
  • GPR174 can signal via GNAS to modulate B cell gene expression
    • cell & other

    Susceptibility
  • to severe malaria
  • to vasovagal syncope
    • Variant & Polymorphism SNP
  • three SNP presenting significant associations with severe malaria were clustered at the 5-prime end (Auburn 2008)
  • mutation T/C inside codon 131 causes the increased activation of adenyl cyclase, which plays an important role in cardiovascular regulation, and predisposes to vasovagal syncope (Lelonek 2008)
