    basic FUNCTION
  • playing a role in the release of ATP from human erythrocytes
  • in stellate ganglion neurons, GNB2 and GNB4 normally maintain the coupling of Ca(2+) channels with the receptors, with the latter subtype responsible for maintaining the integrity of both pathways
  • is required for starvation-induced NFKB1 activation and constitutive NFKB1 activity

    protein
  • interacting with ATXN10 (coexpression of ataxin 10 and GNB2 potently activated the Ras-MAP kinase-Elk-1 cascade, a mechanism for inducing neuritogenesis)
  • KCNJ6 is capable of interacting with GNB1, GNB2, GNB3 and not GNB4 or GNB5
  • GNGT1, GNG2, GNB1, GNB2, GNB3, interacts with MTOR and promotes its activation
