The three putative pseudogenes, or possible 'short' AQPs, are depicted in their subfamilies. *Amino-terminal extensions (longer than approximately 10 amino acids amino-terminal of TM1). †Carboxy-terminal extensions (more than approximately 10 amino acids carboxy-terminal of TM6). ¶AQP with amino-terminal extensions that satisfy, at least superficially (that is, predicted by some programs) criteria for protein transport into mitochondria. No experimental evidence, however, exists for this conjecture. Putative signal sequences for chloroplast import could not be identified.
