FIG. 2.
Predicted amino acid sequence encoded by ORF YBR152w (SPP381). The acidic serine-rich elements common to Prp38p and Spp381p are underlined. The putative PEST sequence is represented by bold italics. Spp381p has a predicted molecular mass of 33.8 kDa and a predicted pI of 5.4. In comparison, Prp38p is a 28-kDa protein with a predicted pI of 5.0 (5).
