FIG. 2.

Predicted amino acid sequences of SNX1, SNX1A, SNX2, SNX3, and SNX4. The predicted amino acid sequences for human SNX1 (hSNX1), SNX1A, SNX2, SNX3, and SNX4 cDNAs are shown. The SNX1 amino acid sequence was identical to the published SNX1 sequence (21), except for the three residues indicated by boldface and double underlining. We found serine at positions 115 and 117. At position 211, we found proline (codon CCC) in one clone and serine (TCC) in two other clones, suggesting that there is a polymorphic amino acid. The entire coding sequence of SNX1A was shown to be identical to that of SNX1, except for an in-frame deletion of 195 nucleotides. The 65 amino acid residues (91 to 115) deleted from SNX1A are underlined.
