Isoforms of soybean seed oil body membrane protein 24 kDa oleosin are encoded by closely related cDNAs

We have characterized two cDNA clones for 24 kDa soybean oleosin, the seed oil body membrane protein. Differences in the predicted amino acid sequences of the two clones and the presence of a doublet on immunoblots indicate that 24 kDa oleosin exists in at least two isoforms in soybean. The predicte...

Summary:We have characterized two cDNA clones for 24 kDa soybean oleosin, the seed oil body membrane protein. Differences in the predicted amino acid sequences of the two clones and the presence of a doublet on immunoblots indicate that 24 kDa oleosin exists in at least two isoforms in soybean. The predicted amino acid sequence also contains a unique carboxy terminal region that is dominated by a series of different tandem amino acid repeats.
