text: Yo, listen up, I got a story to tell
  'Bout chicken histone H5, it's a linkin' spell
  Expressed in nucleated erythrocytes alone
  This histone H5 promoter got spots to own
  
  Sp1, a high affinity site, it's legit
  UPE-binding protein, they both commit
  The enhancer at the 3', erythroid-specific
  Sp1, GATA-1, NF1, they're terrific
  
  In this study, we delve deep, no joke
  Trans-acting factors bindin', we provoke
  Chicken histone H5 promoter and enhancer
  Associated with nuclear matrices, an enhancer
  
  NF1, it's the one, not Sp1, GATA-1, or UPE
  In the erythroid cells, it's NF1, you see
  Mature erythrocyte nuclear matrix, it's a match
  NF1 family proteins, got 'em locked, ain't no catch
  
  Chicken liver, trout liver, they got NF1 too
  Internal nuclear matrices, they groove
  This study's observations, they got the claim
  NF1's role is real, targetin' DNA's the game
