Despite vast differences in primary structure, it is here shown that several predominant
semen proteins are encoded by genes that belongs to a common family. Members have
their transcription unit split into three exons: the first encoding the signal peptide, the second
the secreted protein, while the third exon solely consists of 3′ non-translated nucleotides.
The first and and the third exon are conserved between members, but the second exon is
not. The genes for human semenogelins I and II, rat SVSII, SVSIV, SVSV and guinea pig …

The genes for human semenogelins I and II, rat SVSII, SVSIV, SVSV and guinea pig GP1 and GP2 belong to this gene family.
