Two different gene assembly models for the only LRRCE-containing sequence in Ciona intestinalis. Sequences encoded by separate exons are shown in different colours (red-black-blue) for clarity. The long model assembly (left) contains 8 exons and 15 LRRs in its LRR domain. The same gene assembly model is used for the homologous protein in Ciona savigny. The short model assembly on the right contains 7 exons and 12 LRRs in its LRR domain; one and a half exons are skipped resulting in the removal of the underlined amino acids from the long form. Both models were generated using prediction algorithms. The short model was part of the first draft for the Ciona intestinalis genome [55] (JGI assembly version 1.0, ci148160), but was later withdrawn in JGI version 2.0 in favour of the longer model. Available EST data (see gene and transcript entries ENSCING00000012194, ENSCINT00000023142 in the ENSEMBL database), has confirmed the long assembly model with 15 LRRs.
