Fig 2.

Example of domain and exon structures of a Chlamy-ICE IBP (IBP-4). The gene has five exons (shown by white, gray and dark gray backgrounds) and two DUF3494 domains (underlined). Exons of the same background color are similar. Each DUF3494 domain has two exon-exon boundaries. Lower case residues indicate an N-terminal signal peptide. Other isoforms have one and three DUF3494 domains. Locations of exon-exon boundaries are the same in each DUF3494 domain. The exons were identified by comparison of the DNA and cDNA reads.
