distributed along approximately half the length of the chromosome. Comparisons to Hox gene expression and location in other species suggests that the Hox genes in ascidian genomes are under a dispersing condition. GEVIs A majority of genetically encoded voltage indicator are based on the C. intestinalis voltage-sensitive domain (Ci-VSD). Transferrin There is one transferrin ortholog which is divergent from those of vertebrate models, and even more divergent from non-chordates. Carotenoid metabolism A retinol dehydrogenase is disclosed in Belyaeva et al. 2015.
