text: Centromeres hold the key, specialized chromatin, you see,
  With spCENP-A/Cnp1, histone H3 variant, it's a guarantee.
  Listen up, here's the scoop, five proteins in fission yeast's troop,
  Mis14-18, making moves, making loops.
  
  Mis14, independent, it's true, recruited to kinetochores, no clue,
  CENP-A stands tall, no Mis14 it needs, it's got its own crew.
  But Mis15, Mis16, Mis17, Mis18, they're part of the CENP-A pathway, it's great,
  Mis15 and Mis17, they form a complex, evolutionarily conserved, no debate.
  
  Mis6 joins the party, part of the crew, a complex that's hearty,
  Mis16 and Mis18, they're on the scene, deacetylating histones, keeping it clean.
  In the central core of centromeres, they maintain the state, no fears,
  Upstream factors in kinetochore assembly, leading the way, they appear.
  
  Kinetochores mutants, they're not bothered, Mis16 and Mis18, they got their order,
  Associating with kinetochores, no bother, except for mis18 and mis16, respectively, they falter.
  Human cells, let's take a peek, Mis16's function, it's unique,
  RbAp48, RbAp46, they're required, CENP-A's location, they seek.
