A plasmodial specific mRNA (plasmin C) fromPhysarum polycephalumencodes a small hydrophobic cysteine-rich protein

The nucleotide sequences of three plasmodial specific mRNAs from the slime mold Physarum polycephalum were previously determined: hap P (LAV1 1 cDNA (1), plasmin B (LAV1 2 cDNA) (2) and profilin P (LAV1 5 cDNA) (3). In the present work, we analyse the LAV1 —3a cDNA. It is an apparent full length copy of another abundant plasmodial specific mRNA (4). The deduced protein sequence (150 a.a.) is rich in hydrophobic residues and contains 13% cysteine. A signal peptide-like sequence is found at the N-terminal region. The protein, which we named plasmin C, shows no similarity to other published sequences. The putative signal peptide and polyadenylation signals are underlined. REFERENCES
