Figure 2.

Sequence and translation of tammar USM1 and opossum USM aligned with brushtail possum EST. Note that the "first exon" in the brushtail possum EST is excluded from this alignment, as it appears to be an artefact (see text). Sequences extend from the transcription start site, determined for tammar USM1 by 5' RACE, to the predicted polyadenylation signal. The signal peptide cleavage site is indicated by an arrowhead.
