The nucleotide sequence of gene PBII encoding salivary proline-rich protein P-B was determined. PBII is 7.1 kb long and contains 3 exons. PBII exhibits considerable nucleotide sequence homology not only in exons but also in introns with PBI (accession number D89501), the gene whose nucleotide sequence was determined previously [lsemura and Saitoh (1997) J. Biochem. 121, 1025-1030]. PBI and II constitute a gene family distinct from that to which the majority of salivary proline-rich protein ones belong. The nucleotide sequence data reported in this paper will appear in the DDBJ, EM-BL, and GenBank nucleotide sequence databases under accession number ABO31740.
