    basic FUNCTION
  • 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
  • plays a role in peripheral nerve regeneration, supporting its importance in peripheral nerve functioning
