Figure 2.

Nucleotide and deduced amino acid sequence of the SSL gene and protein. The sequence corresponding to the longest cDNA (911) is represented by capital letters. Amino acid sequence is given in the single letter code, and the termination codon is marked with three asterisks. Differences in cDNA and genomic sequences are indicated by bold letters over (for nucleotide residues) and under (for amino acid residues) the genomic sequence. The sequence from 226 to 300 bp homologous to the 5′-untranscribed Ste region is underlined, and the sequence homologous to the Y-specific region of Su(Ste) is double underlined. The extents of other SSL cDNAs sequenced are as follows: nucleotides 356-1161, 454-1293, 454-1336 plus a 20-bp oligo(dA) tail, and 473-1301. The restriction sites (italicized) that were used for sequencing (see Materials and Methods) and the site of polyadenylylation are indicated.
