text: Yo, listen up, I got a story to tell,
  'Bout a protein called calreticulin, ringin' the bell.
  It's a mammalian player, multifunctional, no doubt,
  Involved in cellular processes, spreadin' all throughout.
  
  It's all 'bout that Ca(2+), the binding's what it does,
  Storing it up, protein folding, ain't no fuss.
  In the endoplasmic reticulum, that's where it's at,
  CRT's the name, keepin' cells on track.
  
  But hold up, plants got in on the action too,
  15 years back, homologues were found, it's true.
  Two CRT families, they got it goin' on,
  CRT1/2 and CRT3, puttin' plants in the zone.
  
  But we don't know much 'bout what they truly do,
  Their physiological functions, still a clue.
  Now let me drop some knowledge, a discovery we made,
  Ebs2, a suppressor, on the scene it played.
  
  Bri1-9, a mutant, a dwarf in the game,
  ER holdin' a faulty receptor, what a shame.
  But here comes Ebs2, allelic and specific,
  Interacts with bri1-9, gettin' scientific.
  
  Glycan-dependent, that's the way they connect,
  Ebs2 keeps bri1-9 in check, no disrespect.
  Loss-of-function mutations, ER retention goes down,
  Dwarfism suppressed, turnin' that frown.
  
  But wait, if we boost Ebs2, the opposite occurs,
  Enhancin' the dwarf phenotype, it's absurd.
  Them other CRTs, calnexins, they don't do much,
  Bri1-9 ain't bothered, barely a touch.
  
  In a domain-swappin' test, we found the key,
  CRT3's C-terminal tail, the magic you see.
  It's crucial for the "bri1-9-retainer" game,
  Functional role revealed, we ain't playin' no shame.
  
  So that's the story, Arabidopsis's CRT crew,
  Functional diversity, among the paralogues, it's true.
  Plant-specific CRT, makin' moves in the scene,
  Droppin' knowledge, keepin' research clean.
