text: Yo, check it out, I got a story to tell
  'Bout them 7-TMR-G protein networks, I'ma give you the intel
  They be molecular sensors, catchin' signals from afar
  In all eukarya, they be shinin' like a star
  
  These pathways be cyclin', switchin' on and off
  Activatin' and sensitizin', then desensitizin', they ain't soft
  We know 'bout the components that trigger the activation
  But when it comes to inhibition, there's some speculation
  
  In Dictyostelium, these receptors got a role to play
  Directin' chemotaxis and development, that's their way
  But they also control the synthesis, periodic and tight
  Of their own ligand, cAMP, it's a chemoattractant's delight
  
  Now listen close, 'cause here's the revelation
  Through studies, we found the key to the inhibition sensation
  It's the Galpha9 protein subunit, yo, it's unique
  Regulatin' an inhibitory pathway, makin' development sleek
  
  Early Dictyostelium development, cAMP's the signal it receives
  And this Galpha9 subunit, it's the one that believes
  In keepin' things in check, stoppin' the response in its track
  Ain't playin' no games, it's got the inhibitory knack
