This locus has a complex structure, and available EST or cDNA sequences suggest several alternative gene products. The alignment shown includes both the current annotation (topmost), and two predicted ORFs suggested in Cvrckova et al. 2004 whose sequence can be downloaded here.
Most notably, our prediction of AtFH15a differs in the position of the exon marked in red, which is supported by a cDNA. Note that the 3´end of the cDNA contains stop codons in all three frames (red dots), which would suggest an alternative gene product.
