text: Yo, check it out, in this study we found out
  A specific monoclonal antibody, no doubt
  Identified p75/AIRM1, that's the name
  An inhibitory receptor with a whole new game
  
  Confined mostly to human killer cells
  This receptor inhibits, you can tell
  A 75-kD glycoprotein, it's the deal
  Gets tyrosine phosphorylated, that's for real
  
  Sodium pervanadate treatment triggers the change
  Associates with SHP-1, ain't that strange?
  On human chromosome 19, the gene resides
  A sialoadhesin family member, no lies
  
  Three immunoglobulin-like domains it got
  One NH(2)-terminal V-type, you like it or not
  Two C2-type domains, that's how it goes
  And a cytoplasmic portion with an ITIM pose
  
  Similarity in amino acid sequence, you see
  To CD33 and CD33L1, it's a guarantee
  Like other sialoadhesin molecules, it's true
  p75/AIRM1 recognizes sialic acid, too
