Identity and similarity analysis of putative domains of AtMRP1 against ScYCF1, HmMRP1, rat canalicular multispecific organic anion transporter (RtCMOAT), and human CFTR (HmCFTR). In addition to the overall sequences (Σ), the regions examined were the N-terminal extension (N), transmembrane segments 1 and 2 (TM1 and TM2, respectively), CFTR-like putative regulatory domain (R), NBF1 and NBF2, and C terminus (C). The compilation was derived from the results of GAP comparisons using the default parameters of the GCG package (version 8.0, University of Wisconsin, Madison, WI). The GenBank/EMBL accession numbers for the proteins shown were: AF008124, AtMRP1; L35237, ScYCF1; L05628, HmMRP1; L49379, RtCMOAT; M28668, HmCFTR.
