- A systematic survey for transcripts of all 16 mammalian carbonic anhydrase isozymes in various organs showed that each organ expresses unique combinations of carbonic anhydrase isozymes.
- During inner ear development, transcripts of four cytosolic isozymes (Car1, Car2, Car3, and Car13), two membrane-bound isozymes (Car12 and Car14), and two CA-related proteins (Car8 and Car11) were expressed at higher levels than other isozymes.
- Each isozyme showed a unique temporal and spatial expression pattern during inner ear development.
- Expression patterns for some isozymes closely overlapped with genes previously associated with inner ear development or function, such as Pendrin, Pou3f4, or Bmp4.
