text: Yo, check it out, I got a story to tell,
  'Bout a molecule that rings the alarm bell.
  TBK1, the crossroad king,
  In the world of signals, this dude's got the swing.
  
  In mammals, we know its innate immunity might,
  But in avian, TBK1's still out of sight.
  So we took a step, and we made a move,
  Cloned duTBK1, now we're in the groove.
  
  From duck embryo fibroblasts, we got the code,
  A 729 amino acid, ready to explode.
  High identity with goose and cormorant,
  TBK1's in the house, it's time to rant.
  
  Cytoplasmic localization, spreadin' all around,
  Expressed in all tissues, can't be bound.
  duTBK1's got the power, it's 'bout to ignite,
  IFN-β production, shinin' so bright.
  
  IRF1 and NF-κB, they step into the game,
  Activated by duTBK1, ain't that insane?
  The kinase domain, the middle's ubiquitin-like,
  They're the keys to success, they take the mic.
  
  Knockdown duTBK1, things start to change,
  Poly(I:C) and Sendai virus ain't in their range.
  IFN-β expression, it takes a dive,
  duTBK1's the hero, keepin' viruses alive.
  
  And when it comes to reovirus and Tembusu,
  duTBK1's the boss, it's the one to choose.
  Reduced replication, it's a victory,
  duTBK1, the savior of duck's immunity.
  
  So there you have it, the story's complete,
  TBK1's the star, can't be beat.
  Innate immunity, it's all about the show,
  duTBK1's rappin', lettin' you know.
