Identification of a brushtail possum coat protein component from published sequences. Published sequences (boxed) of electrophoresed protein bands from possum postovulatory coats  are aligned with a translation of brushtail possum expressed sequence tag (EST), GenBank accession EG617409, highlighted in blue. Aligned residues between the translated EST and the major sequence of band 5 are shown in red. Additional residues within the sub-sequences of bands 3-5 that also match the EST are shown in green. In bands 3 and 5, these are one residue out of phase. The approximate molecular weights indicated are those estimated by Casey et al. .
